Which of the following acids does not form acidic salts?
a-Phosphoric acid
b-Carbonic acid
c-Hydrochloric acid
d-Sulphuric acid​

Answer 1

Mark the rule

• Stronger acids form acidiy salts .

Because carbonic acid is a weak acid.

A weak acid is only partially ionized in a solution.in other words,a weak acid doesn't completely dissociate or break apart into ions in a solution.
