Explain what combination of a molecular base and a salt

Reference no: EM13209472

a) What combination of a molecular base and a salt of the conjugate acid of the chosen molecular base should you select to prepare a buffer solution that would maintain a pH of 10.00? (You will not be given credit if you use a salt of a weak acid and a weak acid for this problem) For full credit, explain your choice in a simple, straightforward manner, (keep answer under 40 words).

b) What ratio of concentrations of the molecular base you chose in part a and its conjugate acid would be necesarry to achieve a pH of exactly 10.00?

c) Describe, using one well-written sentence, a simple abd practical way to make 1.00L of the buffer solution you did calculations for in part b, assuming that a 1.0M solution of the molecular base is available and that the chloride salt of the conjugae acid is available as a solid. (Note: laboratory balances are calibrated to measure in grams and pipettes in mL, neither of these practicle instruments are calibrated in moles)
