Hi, so to solve for this, i'm going to write the equations first that we're going to use.
00:08
Ph is equivalent to negative log of the hydrogen ion concentration or this could also be written as hydronium h3o plus.
00:17
And then poh is equivalent to negative log of hydroxide ion concentration.
00:24
And the sum of the ph and poh of a solution will always be equivalent to 14 at 25 degrees celsius.
00:30
So for the first solution, we have hcl.
00:33
Hcl is a strong acid, so that means the hydrogen ion, i'm just going to use h plus here, is equivalent to the concentration of the acid hcl.
00:43
So we can now solve for the ph.
00:45
That's going to be negative log of 0 .00.
00:49
How many 5, how many zeros do we have? yeah, i think 5.
00:53
And this will give us 5 .0.
01:00
This is the ph of the solution.
01:02
Second one, we have potassium hydroxide...
