- Let, N1 and V1 be the strength and volume of the strong acid .
N2 and V2 represents the same for a strong base.
- N1V1 is the concentration of strong acid and N2V2 is the concentration of strong base
1). If, N2V2 > N1V1
(solution is basic)
= [OH⁻]
The required formulae for the pH of the mixture at the initial stage of acid-base titration = [H⁺] =
∴ pH = -log₁₀[H⁺]
2). If N1V1 > N2V2
(solution is acidic)
[H⁺] =
The required formulae for the pH of the mixture at the initial stage of acid-base titration
∴ pH = -log₁₀[H⁺]
