WebApr 28, 2024 · A 1:1 buffer of H2A and HA- would have better buffer capacity, and a 1:1 buffer of HA- and A(2-) would have better buffer capacity. Of course, they would buffer at a different pH. Also, finding a buffer with a pKa at (pKa1 + pKa2)/2 would be a better buffer as 1:1 buffer at the pH in question. $\endgroup$ – WebBC 367, Experiment 1, Fall 2009 4 your notebook, label the species found on each region of the curve.

WebChemistry questions and answers. Blood is buffered by carbonic acid and the bicarbonate ion. Normal blood plasma is 0.024 M in HCO3− and 0.0012 M in H2CO3. (pKa1 for H2CO3 at body temperature is 6.1.) If the volume of blood in a normal adult is 5.5 L, what mass of HCl could be neutralized by the buffering system in blood before the pH fell ... Web1 day ago · No, H2CO3 is not a strong acid as it does not dissociate completely in an aqueous solution. The carbonic acid molecule has two hydrogen atoms to lose i.e. it is a diprotic acid and, therefore, has two acid dissociation constants, Ka. The value of the acid dissociation constant is the reflection of the strength of an acid.
