Hello everyone, the relation between ph and h plus or h3o plus, this is given by ph is equal to minus log h plus.
00:23
Is equals to minus log h3o plus.
00:28
So we can say that minus ph is equal to log h3o plus.
00:35
So taking antelog on both sides, we will get 10 power minus ph is equal to h3o plus.
00:48
So if we consider this, then in the first problem we have, it is given that ph is equals to 13.
01:02
So 10 power minus ph is equals to h3o plus.
01:08
So from here we will get h3o plus is equal to 1 multiplied by 10 power minus 13 m.
01:21
So this is the answer for the first part.
01:24
And in the second part, ph is equal to 10.
01:29
This means h3o plus is equal to 1 multiplied by 10 power minus 10m.
01:42
In the same way for the third part, is equal to 7 .40 so if ph is equal to 7 .40 then h3o plus will be 10 power minus 7 .40 which is 3 .98 multiplied by 10 power minus 8m so this is for the third part and in the fourth part we have spit for width again, ph is equal to 7 .40, then h3o plus is equal to 3 .98 multiplied by 10 power minus 8m.
02:44
In the fifth part, we have water for which ph is equal to 7.
02:54
So, h3o plus will be 1 multiplied by 10 power minus 7m...
