Explanation:

Acids have a sour taste, not a bitter taste. Bases have a bitter taste.
Acids can donate a proton (\(H^{+}\)) when reacting with a base (according to the Brønsted - Lowry theory).
Acids can corrode metals (e.g., \(Zn + 2HCl=ZnCl_{2}+H_{2}\uparrow\)).
Acids change blue litmus paper to red.

have a bitter taste
