molarity =   W*1000/G.M.Wt*volume of solution in ml

                = 500*10-3 *1000/180.15 *25    = 0.111M

   HA   ------------> H+ + A-

I          0.111                0        0

C         -x                      +x        +x

E        0.111-x                +x       +x

      Ka   = [H+][A-]/[HA]

    3*10-4   = x*x/0.111-x

   3*10-4 *(0.111-x) = x2  

            x= 0.0056

[H+] = x = 0.0056M

PH = -log[H+]

        = -log0.0056   = 2.2518

[H+] = C*ionisation

ionisation% = [H+]*100/C

                       = 0.0056*100/0.111 = 5.045%
