Question

What is the pH of a solution with a 2.20 × 10−8 M hydroxide ion concentration?

Answer 1

1.0 × 10−7 M at 25 °C. The pH and pOH of a ... [H3O+] = 5 × 10–8 M.

Answer 2

Answer:

The pH of the solution is 6.35.

Explanation:

Concentration of hydroxide ions = $[OH^-]=2.20\times 10^{-8} M$

pH + pOH = 14

pH = 14 - pOH

$pOH=-\log[OH^-]$

$pOH=-\log[2.20\times 10^{-8} M]=7.65$

$pH=14-pOH=14-7.65=6.35$

The pH of the solution is 6.35.
