7.70 The ionization constant of benzoic acid is 6.46 × 10-5 and Ksp for silver benzoate is 2.5 × 10-13. How many times is silver benzoate more soluble in a buffer of pH 3.19 compared to its solubility in pure water?
It is given that,
of buffer solution is 3.19. So, the concentration of ion can be calculated as;
