Which list contains ONLY strong acids?

A.HCl, HF, HNO₂
B.HCl, HBr, HI
C.HNO₃, H₂SO₃, HCl
D.HI, HNO₂, CH₃COOH

Explanation

Core Concept

The common strong acids are HCl, HBr, HI, HNO₃, HClO₄, HClO₃, and the first proton of H₂SO₄. Only the list pairing HCl with HBr and HI draws entirely from that set. Each member ionizes essentially completely, so [H₃O⁺] matches the formal acid concentration.

Correct Answer

BHCl, HBr, HI
