Question

A white powder A is a mild non corrosive base and is used in the preparation of cakes. when the powder is hested , it gives another powder B. the powder B is recrystallized to get C which has detergent properties. identify A, B and C and write the balanced chemical equation for the consversions of A and B.

Answer 1

Hope this will help you guys

Answer 2

First, Let us identify the three detergent products. A must be Baking Powder, as Baking soda is very edible and tartaric like acid. If we heat this, it releases CO2 gas. Then B must be Sodium Carbonate, and C would be Washing Powder or Washing Soda. 

A = NaHCO3 (Baking Powder / Baking Soda) 

B = Na2CO3 (Sodium Carbonate) 

C = Na2CO3. 10H2O (Washing Powder / Washing Soda) 

Chemical Equation for the conversion of A and B
