Question

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

Answer 1

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, you get a resulting answer of

1×$10^{-4}M$.
