HCl is a strong acid, so we use the following formula:
[H^+] = a × Molarity
= 1 × 0.35 M
= 0.35 M (the concentration of H^+)
pH = - log [H^+]
= - log 3.5×10^-1
= 1 - log 3.5
= 0.456
[H^+] = a × Molarity
= 1 × 0.35 M
= 0.35 M (the concentration of H^+)
pH = - log [H^+]
= - log 3.5×10^-1
= 1 - log 3.5
= 0.456

Answer:
0.443
Explanation:
- HCl is strong acid
- on dissociation it will give
HCl --------> H⁺ + Cl⁻
Given:
0.36M HCl concentration means
[H⁺] = 0.36
To Find:
pH = ?
Solution:
pH = -log[H⁺]
pH = -log[0.36]
pH = 0.443
