Question

calculate the Ag+ ion concentration in terms of pAg during the titration of 50.00 ml of 0.500 M NaCl with 0.1000 M AgNO3 after addition of the following volumes if reagent:

a) in the pre-equivalent point regim at 10.00 ml

b) at the equivalent point (25.00ml)

c) after the equivalent point at 26.00 ml.

Rsp AgCl= 1.82x10^(-10).

Answer 1

a) At the pre - equivalent point , at 10.0 ml

b) at the equivalent point (25.00ml)

at the equivalent point both Ag⁺ and Cl^- concentration are same.

c) after the equivalent point at 26.00 ml
