What is the hydronium ion concentration of a solution with a poh of 8.30?

1.28 × 10−6 m

1.99 × 10−6 m

2.34 × 10−5 m

2.86 × 10−5 m

Answer : The correct option is,

Solution : Given,

pOH = 8.30

As we know that the pH is the negative logarithm of the hydrogen ion concentration.

First we have to calculate the pH of the solution.

Now we have to calculate the hydronium ion concentration.

Therefore, the hydronium ion concentration is,
