Question

The solubility product for calcium phosphate is 2.0x10^-29.

A. Calculate the molar solubility of calcium phosphate, and theconcentrations of

the calcium and phosphate ions at equilibrium.

B. Using Excel, create a spreadsheet that calculates the calciumand phosphate ion

concentrations at equilibrium following the addition of1.0x10^-8

M to

1.0x10^-7

M calcium chloride, in increments of 1.0x10^-9

M. From this data, plot

the concentration of the phosphate ion versus the concentrationof the calcium

ion at equilibrium. (You may want to multiply the concentrationsby some

constant value to make it easier to read the axes labels.) Printout and turn in

your plot with sample calculations (handwritten) of the calciumand phosphate

ion concentrations calculated for any three points between1.0x10^-8

M to

1.0x10^-7

M calcium chloride. (Make sure you plot adheres to therequired

standards on page 33 of the lab manual.)
