One of the most important buffering systems in the biological realm is the carbonic acid (H2CO3)/carbonate ion (HCO3- ) system that maintains the pH of blood plasma to a relatively constant value. In blood at 37°C, the Ka of carbonic acid is 8x10-8. Suppose that the concentrations of the buffer components in the blood plasma are: [HCO3-] = 0.24 M and [H2CO3] = .12 M. Calculate the pH of blood.

In waters affected by acid rain the concentrations of the three carbonic acid species (H2CO3, HCO3-, CO32-) are determined by concentration of the strong acid deposited by acid rain, as well as the concentration of H2CO3 which is controlled by the solubility of carbon dioxide . Under these conditions (constant H2CO3 and relatively low pH) the only carbonic acid equilbrium of importance is the conjugate base reaction of HCO3-, which is related to, but not identical to - and not...

The question is Did the combination of carbonic acid and bicarbonate function as a buffer? Support your response with data. Buffers are chemical mixtures that resist pH change when exposed to acids or bases. They contain both a weak proton donor and weak proton acceptor. The former neutralizes any strong bases added and the latter neutralizes any strong acids added to the buffer. Our bodies rely upon a combination of three different buffers to maintain stable pH: the bicarbonate buffer...

A 100.00 mL buffer solution at pH 7.80 is prepared such that the [H2CO3] + [HCO3] = 1.000 M. Determine how much strong acid 1.00M HCI or strong base 1.000 M NaOH must be added to change the pH to 7.40. The step-wise acid dissociation constants for carbonic acid are Ka1= 4.2*10^-7 ; Ka2= 4.8*10^-11.

Buffers are common (and extremely important) in biological systems, including in human body. One of the most important biological buffers in human blood is the buffer established between carbonic acid and bicarbonate ion (H2CO3/HCO3–). At 25 oC, H2CO3 has a Ka1 of 4.45x10–7 and a Ka2 of 4.69x10–11. a. Will Ka1 or Ka2 of H2CO3 be instrumental in determining blood pH? Briefly explain your reasoning. b. Let’s pretend that there was an equal ratio of carbonic acid to bicarbonate (note...
