In this question we asked what is the ratio of the hco3 minus to h2co3 and blood of ph 7 .4? okay? so we know ph is pkk plus log of hco3 minus concentration to h2.
00:33
To co3.
00:35
This is based on the anderson acidacquation.
00:39
Okay.
00:40
So we need to know the the p .k.
00:44
Here for the carbonic acid.
00:47
Okay.
00:55
So the pkk of carbonic acid, of course, there are two of them.
01:04
The first pkk and the second pkk.
01:07
So we'll be looking at the first pkk and that is 6 .1, okay, plus log of the h .o .3 minus 2, h2 -co3.
01:26
Okay, so we know the ph to be 7 .4, right? so that means the log of the h -co -3 minus to h2 -co3 will be equal to 7 .4 minus 6 .1.
01:44
Which will be equals to 1 .3...
