Hydrochloric acid is highly soluble in water. What is the chemical equation that represents its ionization in water?
Options
- AHCl(g) + H 2 O(l) → H 3 O+(aq) + Cl-(aq)
- BNaCl(s) + H 2 O(l) → Na+(aq) + Cl-(aq)
- CH 2 SO 4 (aq) + HCl(aq) → H 2 O(l) + H 2 S 2 O 7 (aq)
- DH 2 O(l) + H 2 SO 4 (l) → HCl(g) + NaOH(aq)
Correct answer
A. HCl(g) + H 2 O(l) → H 3 O+(aq) + Cl-(aq)
Step-by-step solution
When hydrochloric acid (HCl) dissolves in water, it ionizes to form hydronium ions (H 3 O+) and chloride ions (Cl-).
