1.	(i) A white powder is an active ingredient of antacids and is used for preparation of baking powder. Name the compounds and explain that how it is manufactured. Give chemical equation. (ii) Write a chemical equation to show the effect of heat on this compound.
Answer» Solution :(i) The compound is `NaHCO_3` (Sodium Hydrogen CARBONATE) (Commonly known as baking soda) Manufacturing of sodium hydrogen carbonate: `NH_3+NaCL+H_2O+CO_2 to NH_4Cl+NaHCO_3` (ii) On HEATING, Baking Soda DECOMPOSES into sodium carbonate, water and carbon dioxide. `2NaHCO_3 to^(DELTA) Na_2CO_3+H_2O+CO_2`
