If the pH of the solution is 10, what is the [OH-] concentration?
swat32

Answer:

1×10^{-4}M

Explanation:

To solve this, you will need to do multiple steps.

Firstly, you will have to convert to pOH from pH, which is done by simply subtracting 14-10 to get a pOH of 4.

Then, use the following formula to calculate the [OH-} concentration:

[OH-]= 10^{-pOH}

When converted to Scientific Notation<u>,</u> you get a resulting answer of

<u>1×</u>10^{-4}M<u>.</u>
