Answer 1

Answer:

a) Adding more acid releases more heat. ... If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporise and spatter it. So Always Add Acid to water, and never the reverse.

b) Both the Curd and sour substances are acids. ... So, if such substances are kept in a copper container, the acid will react and the container will be corroded. Thereby may spoil the food.
