Ingredients used in kitchens always amazes us through their magic. One of them is baking powder which has a compound X as its major constituent. The compound X sometimes also helps in getting relief from acid indigestion or even in ant bite. In the laboratory, when we heat compound X, it gets converted into Y which is anhydrous but absorbs water to become a hydrated salt Z, one of the raw materials of soaps and detergents.

(i) Identify the compound X from the following:

Solution

The correct option is A $N a H C O_{3}$
In kitchen, baking powder is used as ingredient for making tasty pakodas, fluffy cakes and more.
Baking powder has baking soda $(N a H C O_{3}$ ) as a major consituent along with some edible acids into it.
Therefore, compound X is $N a H C O_{3}$ : a mild base.
In acid indigestion, $N a H C O_{3}$ neutralises excess hydrochloric acid in the stomach and in case of ant bite, it neutralises formic acid injected through the ant sting.
