5. How would you prepare a liter of “carbonate buffer” at a pH of 10.10?

H2CO↔ H+ HCO3     Ka = 4.2 x 10-7

HCO3-↔ H+ CO3-2        Ka = 4.8 x 10-11

  a

1stbuffer is preferred to prepare at mole ratio of 0.40 to 1.0, dissolve in enough water to make up a 1-L solution

  b

2ndbuffer is preferred to prepare at mole ratio of 0.60 to 1.0, dissolve in enough water to make up a 1-L solution

  c

1stbuffer preferred to prepare at mole ratio of 0.60 to 1.0, dissolve in enough water to make up a 1-L solution

  d

2nd  buffer is preferred to prepare at mole ratio of 0.40 to 1.0, dissolve in enough water to make up a 1-L solution
