We have to find out the normal range of hydrogen and hydroxide iron -in blood.
00:07
And we are given the normal range of ph 7 .35 to 7 .45 and also the p .k .w is at 13 .63 at 37 degrees celsius.
00:17
Okay, so first of all, we can file the range of hydrogen first because we are already given the ph.
00:25
So the concentration of hydrogenium is given equals to 10 to the power negative ph.
00:35
So if you can find the boundary between that, we have the range for the for the for the hydrogenium.
00:42
So let's say for ph 7 .35.
00:47
So the hydrogenium concentration will be 10 to the power of that 7 .35.
00:54
So we will have a 4 .47 times 10 to the letter 8 motor.
01:02
And then we're going to repeat the same calculation.
01:05
And then we should be able to find that for 7 .4 .45.
01:10
We will have 3 .55 times 10 to the left of 8 motor.
01:17
So for the range of hydrolyum iron, so it will be between 3 .55 to 2 .5 to, 4 .47 times 10 to the negative 8 motor.
01:32
Okay, so at the same time, we have to find out the concentration of hydroxide.
01:39
Okay, so from here, we know that pkw is equals to 13 .63.
01:44
So in other word, the kw will be equals to 10 to power negative 13 .63.
01:50
Okay, so if we remember kw is a cell ionization of water, so you have two water molecule going into ionize to form hydroxide and also hydrogen iron and this is corresponding to kw so in the other word k w will be corresponding to our concentration of hydrillion times the concentration of hydroxide all right so this should be a it should be a reaction equation yeah so it should not be the concentration over here and this will be the kw.
02:28
Okay, so how can we find hydroxide concentration? so it's a pretty straightforward...
