verania Posted October 31, 2007 Share Posted October 31, 2007 Carbonate buffers are important in regulating th pH of blood at 7.40. what is the concentration ratio of CO2(usually written H2CO3) to HCO3- in blood at pH 7.40? H2CO--HCO3+H+ Ka=4.3x10-7 Link to comment Share on other sites More sharing options...
Darkblade48 Posted October 31, 2007 Share Posted October 31, 2007 This definitely sounds like a homework question, so I won't be giving away the answer; however, it is possible to guide you through it. You know that the pH is 7.4 in blood; and you are given the equation for the equilibrium reaction, as well as the Ka for the reaction. From there, just make an ICE table (initial, change, equilibrium) and you can easily solve the question. Remember that pH is a measurement that is dependent on the concentration of protons.
