Answer to Question #70609 in Inorganic Chemistry for Arshad

Question

Determine of pH of acid solutions like 0.1m hcl,0.5m hcl,0.025m hcl,0.0125m hcl by using quinhydrone and calomel electrode .compare the values of pH with theoretically calculated values.

Answer 1

pH = -lg [H + ];
0.1m hcl: pH = 1;
0.5m hcl: pH = 0.3;
0.025m hcl: pH = 1.6;
0.0125m hcl: pH = 1.9.
