Consider this equation in chemical equilibrium. cap h sub 2 SO sub 4 A q if and only if 2 cap h raised to the plus plus SO power sub 4 raised to the 2 minus power What will happen to the chemical equilibrium if HCl is added to the system?

Adding HCl increases the concentration of H⁺ ions, which are products in the equilibrium H₂SO₄ ⇌ 2H⁺ + SO₄²⁻. By Le Châtelier’s principle, the system shifts left to use up some of the added H⁺, so the equilibrium shifts toward H₂SO₄.
