Answer 1

Assertion:- Baking powder is a mixture of a mild acid and sodium bicarbonate

Reason:- Mild acid removes the bitterness which is produced due to the formation of sodium carbonate when sodium bicarbonate is heated.

Both A and R are true and R is the correct explanation of A (Option 1)

Explanation :

• Baking powder is the mixture of a base (carbonate or bicarbonate), mild acid; where cornstarch acts as a buffer avoiding the premature action of the acid-base mixture.

• Bicarbonate or carbonate on heating gives a metallic or bitter taste to the food, because of chemical change.

• The mild acid in the powder comes to the rescue, avoiding the bitterness with its mild sour touch.

• Thus, the given reason supports the assertion, and both are true.
