Answer to Question #260481 in General Chemistry for vtg

Question

1. Discuss the Fajans method as used in the argentometric titrations [4]

2. Consider the titration of 25.00 mL of 0.1 M I-1 with 0.05 M Ag+ . KSP = 8.3 x 10-17 . Calculate the pAg after addition of:

a. 11.20 mL of Ag+ [3]

b. 50.00 mL of Ag+ [2]

c. 53.80 mL of Ag+ [3]

Answer 1

The precipitation titration in which silver ion is titrated with Halide or thiocyanate ions in presence of adsorption indicator is called as fajan's method.This method is generally used for the quantitative analysis of halide ions or thiocyanate ions.
