Determine the pH of a 4.5 x 10-3 M HBr solution.
Determine the pOH of a 4.5 x 10-3 M HBr solution.

pOH = 11.65

The pH of solution is 2.35

Explanation:

Given data:

Concentration of HBr = 4.5×10⁻³ M

pH of solution = ?

Solution:

pH = -log[H⁺]

pH = -log [4.5×10⁻³]

pH = 2.35

The pH of solution is 2.35.

pOH of solution:

14 = pH + pOH

14 = 2.35 + pOH

pOH = 14 - 2.35

pOH = 11.65
