What is the approximate ph of a 0.06 m solution of ch3cooh (given that ka = 1.78 x 10-5)? 1 3 6 7 9

Answer : The pH of the solution is, 3

Solution :  Given,

Concentration (C) = 0.06 M

Acid dissociation constant =

The equilibrium reaction for dissociation of (weak acid) is,

initially conc.         c                                   0                  0

At eqm.                                                          

First we have to calculate the concentration of

As, we know that

   (for weak electrolyte)   ...........(1)

where, is degree of dissociation

      ..................(2)

By equation both the equations (1) and (2), we get

Now put all the given values in this expression, we get

Now we have to calculate the pH.

Therefore, the pH of the solution is, 3

there all right good
