32.
200mL of an aqueous solution of HCL (ph=2) is mixed with 300mL of an aqueous solution of NAOH (ph=12). What will be the Ph of the resulting mixture solution?
ans:

also,

So, the pH was found to be 11.3

33.
Calculate the Ph of 1M acetic acid solution. To what volume one litres of this solution be diluted so that Ph of the solution that is formed will be twice of the original value.(Ka=1.8*10^-5)
ans:

So,the volume to be added is 54954.208ltr

55.
Calculate the pH of 1gm/ltr NaOH solution.
ans:

so the ph is 12.4

56.
