Sagot :
The pH at 25°c of a 0. 11 m solution of a weak acid that has ka = 9. 2 × 10−6 is 3.
What is base dissociation constant?
The base dissociation constant is termed as Kb. Throughout a base split into ts constituent ions in water is determined by its base dissociation constant.
Kb = [H+] [A-]/[HA]
Now, let the concentration of [H+] = [A-] = x
Given,
Ka = 9.2 × 10−6.
Firstly we will calculate the value of the concentration of [H+]
pKa = x^2/(0.11-x)
9.2 × 10−6 = x^2/(0.11-x)
x^2 = 1.012 × 10−6
x = 1.002 × 10^−3.
The concentration of [H+] = [A-] = 1.002 × 10^−3.
Now, we will find pH as
pH = -log[H+]
pH = -log(1.002 × 10^−3)
pH = 3
Thus we calculated that the pH of the solution is 3.
