Final answer:
The solubility of silver phosphate, Ag3PO4, in pure water is approximately 1.6 x 10^-6 M.
Step-by-step explanation:
The solubility of silver phosphate, Ag3PO4, in pure water can be calculated using the solubility product constant (Ksp). The Ksp for Ag3PO4 is given as 2.6 x 10^-18. The solubility of Ag3PO4 can be determined by finding the equilibrium concentration of the silver ion (Ag+) and the phosphate ion (PO4^3-).
To calculate the solubility, we can assume x mol/L to represent the concentration of Ag3PO4. Since the stoichiometry of Ag3PO4 is 1:1, both Ag+ and PO4^3- will have a concentration of x mol/L.
Thus, the solubility of Ag3PO4 in pure water is approximately 1.6 x 10^-6 M.
