Answer:

12.1; acidic

Explanation:

I'm assuming the hydrogen concentration is H+.

So, first we must find pH.

pH = -log[H+]

I simply just plugged in the concentration.

I get 1.9 as the pH. This means that the substance is very acidic since it has a low pH.

Now to find poH.

poH + pH = 14

I simply plugged in once again!

I get 12.1 as the poH. This also determines that the substance is very acidic since it has a high poH.
