Question

the pH of a solution prepted by mixing 45ml of 0.183 M KOH and 65mL of 0.145 M HCI is.........

Answer 1

find moles:

0.045 litres @ 0.183 mol/litre = 0.008235 moles base

0.065 litres @ 0.145 mol/litre = 0.009425 moles acid

subtracing shows that you have 1.19e-3 moles of acid left in the 110 ml

1.19e-3 moles of acid / 0.110 litres = 0.01082 Molar

0.01082 Molar H+ gives a pH  of 1.9658

your answer : pH  is 1.97
