We are given an s is called h -o -b -r, and then we would like to find out the concentration of hydronium, concentration of o -b -l -m -m -l -concentration constant to be specific, and also the p -e -k -a.
00:18
Okay, so we are also given another important information is ph equals to 4 .8.
00:23
In order to answer this question, we just need to set up an ice table.
00:27
So first of all, we will have a 0 .1 motor of h -o -b -r, and then we have nothing on the right.
00:35
And then the chain will be minus x, plus x, and plus x.
00:39
And the equilibrium concentration will be equals to 0 .1 minus x, x and x.
00:46
Okay, so the h -h -plus essentially equals to h -3o -plus.
00:52
So you're just talking about the hydrogenium ion.
00:55
Okay, so the concentration of hydrogenium, actually we have ph 4 .8.
01:01
So actually we're going to take the 10 to the power of relative 4 .8 because ph equals to letive log of concentration of hydroleum.
01:11
So we're going to file the concentration of hydrogen.
01:15
So that's why we're going to take the 10 to the power of relative 4 .8.
01:21
So 10 to the power of letter 4 .8, it will be equal to 1 .1.
01:26
0 .58 times 10 to power of net 5 molar.
01:32
And that will be the concentration of hydrogen...
