Hello, in this question we are given the ph of a solution.
00:07
We are told that it is 11 .7.
00:11
And what we want to know is the hydronium ion concentration.
00:16
Well, the hydronium ion is h3o plus.
00:20
And we want to know its concentration.
00:23
Well, to do this, we need an equation that connects both ph and h3o plus.
00:29
And that equation is ph is calculated by taking the negative log of that hydronium ion concentration.
00:39
Okay, to rearrange this to solve for h3o plus, i want to divide each side by negative one.
00:45
That gives me the negative ph is equal to the log of h3o plus.
00:53
All right, and then furthermore, to isolate h3o plus, we need to give her that log.
00:59
So if we take anti -log or inverse log of each side of the equation, on the right -hand side, anti -log times log will cancel each other out, leaving simply h3o plus concentration...
