Baking powder is a mixture of
(i) `NaHCO_(3)` , (ii) starch
(iii) `Ca(H_(2)PO_(4))_(2) , (iv) NaAI(SO_(4))_(2)`

A

`Ca(H_(2)PO_(4))_(2)` is acidic and when moistened it reacts with `NaHCO_(3)` evolving `CO_(2)` gas.

B

NaAl `(SO_(4))_(2)` slows down the decomposition reaction of `NaHCO_(3)` so that `CO_(2)` is evolved more sloely.

C

NaAl `(SO_(4))_(2)` is acidic and when moistened it reacts with `NaHCO_(3)` evolving `CO_(2)`

D

Both (a) and (b)
