This question is a fairly lengthy question where you need to complete the table.
00:07
However, the nice thing about completing the table is the concentration of the hydronium ion multiplied by the concentration of the hydroxide ion needs to equal 1 times 10 to negative 14.
00:23
Or, if you want to think of it this way, the sum of the exponents needs to equal negative 14.
00:31
So if we have negative 1, 1 times 10 to negative 1, this needs to be 1 times 10 to negative 13.
00:38
If we have 1 times 10 to negative 2, this needs to be 1 times 10 negative 12, and so forth.
00:43
You'll notice that the sum of the exponents in all cases equals negative 14.
00:52
Then to determine the ph, the ph is just the positive of the exponent so long as it's 1 times 10 to the negative something.

So the ph is 9 and 8 and 7...
