Question

Carbon dioxide has a sour taste because of its ______ (basic/acidic) nature.

Answer 1

• Carbon dioxide when dissolved in water imparts sour taste because of the formation of carbonic acid which in turn dissociates to produce proton and bicarbonate ion.
• It eventually results in a drop of pH increasing the acidity of the solution.

Thus, carbon dioxide has a sour taste because of its acidic nature.
