The pOH of pure water at 40 oc is 6.8. What is the hydronium concentration, [H30 ], in pure water at this temperature

Sagot :

The pOH of pure water at 40 degree C is 6.8, then the hydronium ion concentration in pure water at this temperature is 6.3 × 10⁻⁸M.

What is the relation between pH and pOH?

Relation between the pH and pOH will be represented by the following equation:

pH + pOH = 14

Given that, pOH of water = 6.8

Then pH will be pH = 14 - 6.8 = 7.2

We know that, pH = -log[H⁺]

[H⁺] = [tex]10^{-pH}[/tex]

[H⁺] = [tex]10^{-7.2}[/tex] = 6.3 × 10⁻⁸M

Hence concentration of hydronium ion at that temperature is 6.3 × 10⁻⁸M.
