Question

The basicity of an acid is defined as:

• A. the number of replaceable ${OH}^{-}$
• B. the number of $H^{+}$ ions that can be formed from the acid
• C. the power of the acid to form salts
• D. none of the above

Answer 1

Answer: (B)

the number of $H^{+}$ ions that can be formed from the acid

Basicity of an acid is the number of hydrogen ions which can be produced by one molecule of acid. e.g. Acetic acid is monobasic in nature as it can lose one proton or hydrogen atom to form acetate ion.
