The pH at the equivalence point of a titration may differ from `7.0` because of

Why the pH at the equivalence point of a titration may differ from 7 ?

What will be the pH at the equivalence point during the titration of a 100 mL 0.2 M solution of CH_(3)CCONa with 0.2 M solution of HCl ? K_(a)=2xx10^(-5)

What will be the pH at the equivalence point during the titration of a 100 mL 0.2 M solution of CH_(3)CCOONa with 0.2 M solution of HCl ? K_(a)=2xx10^(-5)

What is the pH at the equivalenve point for the titration of 0.20 M aniline (K_(b) = 7.95 xx 10^(-10)) with 0.20 M HCL

Calcualte the pH at the equivalence point when a solution of 0.1M acetic is titrated with a solution of 0.1M NaOH.(K_(a)for acid = 1.9xx10^(-5)) .

Calculate the pH at the equivalence point during the titration of 0.1M, 25 mL CH_(3)COOH with 0.05M NaOH solution. [K_(a)(CH_(3)COOH) = 1.8 xx 10^(-5)]
