Answer:
The addition of a strong acid like HCl to an aqueous solution would result in the decreasing of pH. Solution becomes more acidic.
Explanation:
HCl dissociates in water as this:
HCl → H⁺ + Cl⁻
Imagine and aqueous solution of NaCl where you have:
NaCl → Na⁺ + Cl⁻
2H₂O ⇄ H₃O⁺ + OH⁻
The addition of HCl would increase the [H₃O⁺]
2H₂O ⇄ H₃O⁺ ↑ + OH⁻
If the [H₃O⁺] is higher, the pH would be lower so the solution would be more acidic
