What are the concentrations of hydroxide and hydronium ions in a solution with a ph of 10.2?
1.4 × 10–4 m h3o+ and 7.1 × 10–11 m oh–
3.8 × 10–6 m h3o+ and 2.6 × 10–9 m oh–
8.3 × 10–9 m h3o+ and 1.2 × 10–6 m oh–
6.3 × 10–11 m h3o+ and 1.6 × 10–4 m oh–

The correct option is, (D)  and

Explanation:  pH is the measure of acidity or alkalinity of a solution.

Now we have to calculate the concentration of ions.

Now we have to calculate the concentration.

Therefore, the concentration is and concentration is,
