Question

Calculate the concentration (in m) of hydroxide ions in a solution at 25. 0 °C with a poh of 3. 58.

Answer 1

The concentration (in M) of hydroxide ions in a solution at 25°C with a pOH of 3.58 is 2.6 × 10⁻⁴ M.

pOH is the measure of basic nature of a solution by evaluating the [OH⁻] concentration.

It is the negative logarithm of the hydroxide ion concentration.

Given,

pOH = 3.58

Temperature = 25°C = 298K

At 25°C, the relation of pOH and [OH⁻] concentration is as follows:

∴ pOH = -log [OH⁻]

⇒ 3.58 = -log [OH⁻]

⇒log [OH⁻] = -3.58

⇒ [OH⁻] = antilog (-3.58)

⇒[OH⁻] = 2.6 × 10⁻⁴ M

The concentration (in m) of hydroxide ions in a solution at 25.0 °C with a pOH of 3. 58 is 2.6 × 10⁻⁴ M.
