Question #70609
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.
Expert's answer
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.
0.1m hcl: pH = 1;
0.5m hcl: pH = 0.3;
0.025m hcl: pH = 1.6;
0.0125m hcl: pH = 1.9.
