Question

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

1 x 10^-4M

1 x 10^-10 M

1 x 10^-9M

1 x 10^-7 M

Answer 1

1 x 10^-4M

Step-by-step explanation:

Answer 2

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`.
