In chemistry, pH is a numeric scale used to specify the acidity or alkalinity of an aqueous solution. It is the negative of the logarithm to base 10 of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic.
(i)calculate the pH of the following solution 100 ml of 0.1 M acetic acid is mixed up with 10 ml of 0.1 M hcl (ka for acetic acid=1.8*10^-5)
(ii)calculate pH of 10^-8 M of NaOH.
(iii)what will be the pH of the following mixture .1000 ml of solution which is 0.1 M wrt HCL and 0.05M wrt Naoh
(iv)calculate ph of 0.1 m HCL and 40 ml 0.2 (M) h2 so4
