Reactivity of Metals

Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about reactivity of metals in this chemistry tuition lesson.

Your chemistry tuition teacher at Miracle Learning Centre will teach you about the reactivity of metals. The reactivity series lists metals from the most reactive to the least reactive. The list goes like this: potassium, sodium, calcium, magnesium, aluminium, zinc, iron, tin, lead, hydrogen, copper, silver, gold. This list is not exhaustive. Just by looking at this list, can you tell why copper, silver and gold are common metals that we see every day but we do not come into contact with potassium or sodium.

This is because sodium and potassium are very reactive metals. When they are exposed to air, they undergo a vigorous reaction with oxygen in the air. Hence they are stored under oil. These reactive metals are stable as compounds. That is why we are so familiar with our common table salt, sodium chloride. Compounds of reactive metals are very stable.

Silver and gold are less reactive metals and hence they can be used to make jewellery because of their shiny appearance. Since they are less reactive, it is safe for anyone to wear it. On the other hand, compounds of silver and gold are unstable and tend to react easily.

The student at Miracle Learning Centre asked, " Which reaction is more likely to happen: sodium oxide with carbon or copper(II) oxide with carbon? " The chemistry tuition teacher at Miracle Learning Centre replied, " From what i taught you earlier, are you able to deduce the answer? The answer is copper(II) oxide is more likely to react with carbon. This is because compounds of less reactive metals are more reactive. Compounds of very reactive metal are more stable."
Miracle Learning Centre hope you have understood the reactivity of metals and how it helps you to answer chemistry tuition questions. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about reactivity of metals and chemistry.

What is Heavy Water?

We are back with another exciting story for your chemistry tuition. Your chemistry tuition can come up with interesting facts about chemistry. Everyone of you knows about water. We know that ordinary water, the one we use every day is composed of two molecules of hydrogen and one molecule of oxygen and can be symbolized by H2O, it’s chemical formula. But, have you got any idea about heavy water? Today in your chemistry tuition we will talk about heavy water. In heavy water the hydrogen of ordinary water gets replaced by deuterium, which is an isotope of hydrogen. It has the chemical formula D2O. In fact, hydrogen has three isotopes: Protium (ordinary hydrogen), deuterium (heavy hydrogen) and the third one being tritium. The nucleus of Protium has only one proton, whereas the nucleus of deuterium possesses one proton and neutron each. Subsequently, the nucleus of tritium contains two neutrons, along with the single proton. In nature 99.85% of hydrogen belongs to protium and only about 0.015% as deuterium. The tritium is present is trace amounts in naturally occurring hydrogen (1 part in 107) and is a radioactive compound. Heavy water (deuterium oxide) is produced due to a combination of deuterium with oxygen.

In natural sources of water for every 6760 parts of ordinary water, there exists one part of heavy water. The molecular weight of H2O is 18 while that of D2O is 20. The density, boiling and freezing point of D2O are higher than that of H2O.

Harold Clayton Urey, an American Chemist discovered D2O in 1931 and got the Nobel Prize in chemistry for his work in 1934. A few millilitres of pure heavy water were prepared by Lewis and Donald in 1933 by constant electrolysis of water for a long duration. Electrolysis of ordinary water for prolonged period gives rise to heavy water as the gas produced during electrolysis in cathode is pure hydrogen and the residual water present in the solution is deuterium oxide. It can be produced at an industrial scale.
Heavy Water is specifically used in nuclear reactors as moderator to slow down the fast moving neutrons. In laboratories, it can be used as an isotopic tracer and in deuterium and other compound preparation.

We hope you enjoyed this lesson from chemistry tuition. We will be back with more such interesting findings in our next chemistry tuition.

What is a catalyst?

Your chemistry tuition is back with another interesting story as always. Do you know about catalysts? Your chemistry tuition will give you some interesting information on catalysts. A catalyst can be regarded as a material that can alter a chemical reaction rate, merely by its presence and without undergoing any change itself. This process is known as catalysis.
Catalysts are of several types, but are mainly classified in two categories: positive and negative. The positive catalysts are those substances that increase the speed of a chemical reaction while the negative catalysts retard it. For example, when potassium chlorinate is heated to about 400oC, oxygen is evolved but when the manganese dioxide is added to it oxygen is evolved only at 200oC. Manganese dioxide acts as a positive catalyst in this reaction. On the other hand, Gypsum which is added to Portland cement to slow down the hardening process acts as a negative catalyst. In some chemical reaction, the product itself acts as a catalyst. This is called auto catalysis. For example, the decolonization of potassium termagant solution by oxalic acid is very slow in the beginning, but once it starts, it becomes very fast. This is due to the fact that Mn2+ ions act as auto catalyst.
If the catalyst and the reactants are present in the same phase, then the catalysis are called homogeneous catalysis. But if they belong to different phases, then it is known as heterogeneous catalysis.

So how does a chemical substance increases the rate of a reaction simply by its presence?

Catalysts may work in two ways. Surface or contact catalysts work by adsorption. The reacting chemicals are adsorbed to form a concentrated layer at the surface of the catalyst. Due to this the chemicals react more quickly. For example, hydrogen and oxygen combine at the surface of powdered platinum to make water.
According to another theory, a catalyst forms an unstable intermediate compound with one of the reactants. This compound reacts with other reactants more quickly forming the final product. At the end, the catalyst is recovered in the original state by different chemical methods.
Catalysis is very important for the production of plastics, rubber, gasoline, oils, fats, sulfuric acid and ammonia. Catalytic reactions also occur in our body. Enzymes act as catalyst to enhance the digestion process. Enzymes also increase the rate of various processes in the cells of plants and animals. We hope you enjoyed this lesson from chemistry tuition. We will be back with more such interesting findings in our next chemistry tuition.

Why do some acids cause burn?

You have all know about acids through your chemistry tuition classes. You are always told to be careful while handling acid in your chemistry tuition classes. As explained by your chemistry tuition teacher, acid is a sour substance that turns red litmus paper, reacts with certain reactive metals to liberate hydrogen, reacts with a base to give salts and water. It also promotes some certain types of chemical reactions. There are two main chemical groups of acids. They are inorganic acids and organic acids. The organic acids contain carbon while the inorganic acids don not. All acids when dissolved in water release hydrogen ions. Hydrochloric acid, nitric acid and sulfuric acid are the examples of inorganic acids. They are also called mineral acids and are very strong acids. Formic acid, acetic acid, citric acid are examples of organic acids and are weaker. Most of the organic acids are harmless to us, but the inorganic acids can be dangerous. Concentrated inorganic acids can burn or wound the skin. Do you know why some acids burn the body? Again, your chemistry tuition teacher will give the answer to that. The inorganic acids have a strong tendency to absorb water and give out a great deal of heat in the process. Since most of the living cells contain water, the strong acids like hydrochloric acid, nitric acid and sulfuric acid react with them and kill the cells causing severe burns. The emission of heat in the process also aids in the burn caused by acids. Special precautions should be taken by the persons handling strong acids. They should wear special clothes to protect their bodies from burns. The acid must always be poured slowly into the water and never the other way round. If you are burned by an acid you should wash your akin with lots of water, followed by a weak ammonia solution. If your eyes are affected, flush them immediately with a lot of water and then with bicarbonate of soda solution, which neutralizes any acid left. Hope you enjoyed this lesson from chemistry tuition. We will be back with more such interesting findings in our next chemistry tuition class.
