Some of the questions and their solutions from NCERT Solutions for Class 10: Carbon and its Compounds, are as follows:
Q. Would you be able to check if water is hard by using a detergent?
Sol. No, we can’t use detergents for checking if water is hard as we know that detergents are sulphonate salts of long chain carboxylic acids. They do not react with calcium and magnesium ions present in hard water to form scum. They give lather with hard as well as soft water. This means that detergents can be used in both soft and hard water.
Q. While cooking, if the bottom of the vessel is getting blackened on the outside, it means that
(a) the food is not cooked completely.
(b) The fuel is not burning completely.
(c) The fuel is wet.
(d) The fuel is burning completely.
Sol. (b)While cooking, if the bottom of the vessel is getting blackened on the outside, then it means that the fuel is not burning completely.
Q. Why are carbon and its compounds used as fuels for most applications?
Sol. Generally carbon compounds give a lot of heat and light when burnt in air. They have high calorific values. When saturated hydrocarbons burn, they produce a clean flame and no smoke is produced. The hence, carbon and its compounds are used as fuels for most applications.
Q. What change will you observe if you test soap with litmus paper (red and blue)?
Sol. Soap is basic in nature. Thus, it turns red litmus blue. The colour of blue litmus will remain blue.
