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,

it's filtration, but this is an assumption so my apologies if i got this
