The Mystery of Weak Acids

Which of the following acids does not form acidic salts?

a-Phosphoric acid
b-Carbonic acid
c-Hydrochloric acid
d-Sulphuric acid​

Answer

Because carbonic acid is a weak acid.

When it comes to the formation of acidic salts, it's important to consider the strength of the acid involved. In this case, the question asks which acid does not form acidic salts, and the answer is carbonic acid.

A weak acid, like carbonic acid, is only partially ionized in a solution. This means that a weak acid doesn't completely dissociate or break apart into ions in a solution, unlike strong acids that completely dissociate in a solution.

One key rule to remember is that stronger acids tend to form acidic salts, while weaker acids tend to form basic salts. Carbonic acid, with the chemical formula containing C, is classified as a weak acid. Therefore, it is unable to form acidic salts due to its weak nature.
