Question

A solution has a Molarity of 1.3 x 10^-6 M. Calculate the pH

A) 5.89
B) 4.9
C) 5.98
D) 9.14

Answer 1

A = 5.89

Step-by-step explanation:

Given data:

Molarity of solution = 1.3 ×10⁻⁶ M

pH of solution = ?

Solution:

pH = -log [⁺H]

By putting values,

pH = -log[1.3 ×10⁻⁶ M]

pH = 5.89

Thus, option A is correct.
