What is Binary Acid?
A binary acid is an acid composed of only two elements: hydrogen and a nonmetal. Binary acids are named using the prefix "hydro-" followed by the name of the nonmetal with the suffix "-ic acid". Examples include hydrochloric acid (HCl), hydrobromic acid (HBr), hydrofluoric acid (HF), and hydrosulfuric acid (H₂S).

Frequently Asked Questions
A binary acid is an acid composed of only two elements: hydrogen and a nonmetal. Binary acids are named using the prefix "hydro-" followed by the name of the nonmetal with the suffix "-ic acid". Examples include hydrochloric acid (HCl), hydrobromic acid (HBr), hydrofluoric acid (HF), and hydrosulfuric acid (H₂S).
Binary acids are widely used in industrial processes: HCl (steel pickling, PVC production), HF (semiconductor etching, uranium enrichment), HBr (pharmaceutical synthesis). They are used as laboratory reagents for pH adjustment, metal dissolution, and synthesis of salts.
Binary acids are corrosive and toxic. HF is extremely hazardous; it penetrates skin and reacts with calcium in bones (calcium gluconate antidote required). HCl and HBr fumes are respiratory irritants. All binary acids require fume hood use, acid-resistant gloves, and eye protection.
