What is the hydrogen ion concentration of a solution with pH=8.25 ?

77julia77 [94]

Answer:

The answer is

<h2> $5.62 \times {10}^{ - 9} \: M$ </h2>

Explanation:

The pH of a solution can be found by using the formula

$pH = - log( {H}^{ + } )$

where

${H}^{ + }$ is the hydrogen ion concentration of the solution

From the question

pH = 8.25

The hydrogen ion concentration of the solution is

$8.25 = - log( {H}^{ + } )$

Find antilog of both sides

That's

${H}^{ + } = {10}^{ - 8.25} \\ = 5.62 \times {10}^{ - 9} \: M$

We have the final answer as

$5.62 \times {10}^{ - 9} \: M \\$

Hope this helps you
