What is Monobasic Acid?
An acid that has only one replaceable hydrogen atom per molecule. It reacts with bases in a 1:1 molar ratio. Examples include hydrochloric acid (HCl) and nitric acid (HNO₃). Equivalent to monoprotic acid in Brønsted-Lowry terminology.

An acid that has only one replaceable hydrogen atom per molecule. It reacts with bases in a 1:1 molar ratio. Examples include hydrochloric acid (HCl) and nitric acid (HNO₃). Equivalent to monoprotic acid in Brønsted-Lowry terminology.
Monobasic acids are used extensively in: laboratory acid-base chemistry (HCl for standardisation and reaction, HNO₃ for metal dissolution, CH₃COOH in buffer solutions), industrial processes, food acidulants (acetic acid in vinegar), and pharmaceutical formulations.
Strong monobasic acids (HCl, HNO₃) are corrosive at all concentrations; dilute solutions still cause skin/eye irritation. Concentrated HNO₃ is both corrosive and oxidising — reaction with organic materials can be explosive. Always use appropriate acid-resistant PPE when handling mineral acids.
