Blood plasma concentration of H2CO3

Question

At 37 C if the blood plasma pH is 7.4 and the plasma concentration of HCO3- is 15mM, what is the blood plasma concentration of H2CO3?

I really don't know how to work this out. can any1 help.

ps. the numbers are subscript

Answer 1

Regulation of Acid Base Balance

Regulation of acid-base balance, regulation of hydrogen ion concentration in the body fluids is actually meant. The hydrogen ion concentration in different solutions can vary from less than 10-14 Eq/litre to higher than 100 Eq/litre.

Only slight changes in hydrogen ion concentration from the normal value can cause marked alterations in the rates of chemical reactions in the cells, some being depressed and others accelerated. For this reason the regulation of hydrogen ion concentration is one of the most important aspects of homeostasis.
