Question

acetic acid has a dissociation constant of 1.8×10-5 .calculate the pH value of decinormal solution of acetic acid​

Answer 1

Answer:

Explanation:

Now acetic acid is a very weak acid so its extent of dissociation is vey low and x should be neglected from denominator. Considering the above aspect the obtained equation is given as : 1.8 x 10 -5 = [x] [x] / 0.1 x 2 = 1.8 x 10 -5 x 0.1

Answer 2

Answer:

1.8× 10- 5 = 13.

$1.8 \times 10 - 5 = 13$
