Baking powder I used for baking. If your mother uses baking soda instead.
(a) will It affect the taste of the cake ? How ? Why ?
(b) How can baking soda be converted into baking powder ?
(c ) What is the role of tartaric acid added to baking soda ?

Explanation

(a) Yes, it affects the taste of the cake. It makes the ckae taste bitter. This is because of the sodium carbonate that is formed as a product of heating baking soda during the process of baking.
`2NaHCO_(3) overset("heat")rarr Na_(2)CO_(3) + H_(2)O + CO_(2)`
(b) Addition of a mild edible acid (tartaric acid) to baking soda makes it baking powder.
(c ) Tartaric acid neutralises the `Na_(2)CO_(3)` and forms sodium tartrate salt. Hence the cake does not taste bitter.
