Which of following acids forms normal salts only?
Tetraoxosulphate (VI) acid
Trioxosulphate (IV) acid
Acetic acid
Tetraoxophosphate (V) acid
Correct answer is C
So we can determine that the basicity of Acetic acid is 1 because it releases one hydrogen ion in an aqueous solution.
Due to this they act as very weak acids. When weak acid reacts with strong base, they tend to form normal salt.
