Question- 1) What combination of a molecular base and a salt of the conjugate acid of the molecular base should you select to prepare a buffer solution that would maintain a pH of approximately 9.50? Please Explain.

a) What ratio of concentrations of the molecular base you selected and its conjugate acid would be necessary to achiece this pH?

b) Describe how you would make 1.00 L of this buffer solution. Assume that 1.0 M solution of the molecular base is available and that the chloride salt of the conjugate acid is available as a solid.

Please show the entire work. I am thanking you in advance
