Why can excess use of only baking soda give a bitter taste to cake?
Answer and explanation
Correct answer: Because a basic substance may be formed
When baking soda is used in excess, heating can leave sodium carbonate or another alkaline residue if it is not fully neutralised by an acid. Alkaline substances generally produce an unpleasant bitter or soapy taste, so option A is correct. Baking powder includes an edible acid that reacts with the bicarbonate and reduces this alkaline residue. Formation of common salt, freezing of water, and acid rain are unrelated to the taste change in cake.
