For making the cake, baking powder is taken. If at home your mother uses baking soda instead of baking powder in the cake.

(a) How will it affect the taste of the cake and why?


(b) How can baking soda be converted into baking powder?


(c) What is the role of tartaric acid added to the baking soda?

(a) On adding baking soda to the cake instead of baking powder, the cake would taste bitter because sodium bicarbonate is a mild base and on being heated gets decomposed giving a bitter taste to the cake.

(b) Baking soda can be converted to baking powder by adding tartaric acid and starch to it.


(c) Tartaric acid plays a major role in maintaining the taste of the cake as it reacts with the decomposed sodium bicarbonate during heating thereby nullifying the effect of bitter taste on the overall taste of the cake.
