Solution of sodium carbonate, potassium chloride, and ammonium sulphate are taken in separate beakers. Recall the colour change of litmus paper in each solution and tabulate. Salt Colour of the litmus paper Nature of the substance A B C

Acids are the substances which are sour in taste and which turns blue litmus into red. Bases are the substances which are bitter in taste and turns red litmus into blue. Here, some salt solutions are given. Their nature and the behaviour towards the litmus paper can be given as, Salt Colour of the litmus paper Nature of the substance A Red litmus turns to blue Basic B No colour change Neutral C Blue litmus turns to red Acidic

Solution of sodium carbonate, potassium chloride, and ammonium sulphate are taken in separate beakers. Name the acid and alkali that react to form each salt given above?

A salt can be formed by the neutralisation reaction of an acid a base. The type of salt formed depends upon the nature or strength of the acid and the base reacted to form the salt. Therefore, the acid and alkali that reacted to form the given salts are, Salt Name of the acid Name of the alkali Na 2 CO 3 Carbonic acid Sodium hydroxide KCl Hydrochloric acid Potassium hydroxide NH 4 2 SO 4 Sulphuric acid Ammonium hydroxide
