(a) carbonate buffers are important in regulating the ph of blood at 7.40. what is the concentration ratio of co2 (usually written h2co3) to hco3- in blood at ph = 7.40? h2co3(aq) equilibrium reaction arrow hco3-(aq) + h+(aq) ka = 4.3 ✕ 10-7 webassign will check your answer for the correct number of significant figures. (b) phosphate buffers are important in regulating the ph of intracellular fluids at ph values generally between 7.1 and 7.2. what is the concentration ratio of h2po4- to hpo42- in intracellular fluid at ph = 7.15? h2po4-(aq) equilibrium reaction arrow hpo42-(aq) + h+(aq) ka = 6.2 ✕ 10-8 webassign will check your answer for the correct number of significant figures. (c) why is a buffer composed of h3po4 and h2po4- ineffective in buffering the ph of intracellular fluid? h3po4(aq) equilibrium reaction arrow h2po4-(aq) + h+(aq) ka = 7.5 ✕ 10-3
