Assertion: Baking powder is used in making cake instead of using baking soda.
Reason: Baking powder contains tartaric acid which reacts with sodium carbonate and removes bitter taste.
Answers
Answer:
both are true................
Assertion and reason both are correct and the reason is the correct explanation of assertion.
The chemical constituent of baking soda is sodium bicarbonate [Na(HCO₃)₂].
The chemical constituents of baking powder are sodium bicarbonate and tartaric acid.
Both of these are leavening agents,i.e., used to rise the dough.
In presence of a suitable acidic activating agent, the sodium bicarbonate component of these reacts to produce sodium carbonate and carbon dioxide. Carbon dioxide bubbles produced help in the rising of the dough, making the bread/ cake spongy. Sodium carbonate is a by-product.
The sodium carbonate if produced above a certain amount leads to a bitter taste. So, baking powder consists of tartaric acid which reacts with sodium carbonate to produce a tasteless compound that does not spoil the taste. Thus, baking powder is prefered over the baking soda.
Hence, the reason is the correct explanation of assertion.
