Question

Nitric acid is a ___.

• A. Monobasic acid
• B. Dibasic acid
• C. Tribasic acid
• D. Weak acid

Answer 1

The correct option is A

Monobasic acid

Basicity of an acid is defined as the number of replaceable hydrogen atoms present in a molecule of an acid. So, a monobasic acid is an acid which contains one replaceable $H^{+}$ ion. Nitric acid contains one replaceable hydrogen atom. Hence, it is a monobasic acid.
