Question 63

Kaplan log approximation to solve for pH from concentration.

E.g. What is pH when [H+] = 6..5 * 10^-4

Answer 63

–log(m x 10-n) ≈ n – 0.m

E.g.
–log(6.5 x 10-4)
≈ 4– 0.65
≈ 3.35

(Actual value is 3.187)

Question 64

Kaplan log approximation to solve for concentration from pH.

E.g. What is [H+] when pH = 5.21

Answer 64

n - 0.m ≈ -log(m * 10^-n)

E.g.
pH = 5.21 = n - 0.m
= 6 - 0.79
≈ -log(7.9 * 10^-6)

Actual is 6.17 * 10^-6
