Question

What is the silver ion concentration in a solution prepared by mixing 423 mL of 0.386 M silver nitrate with 459 mL of 0.509 M sodium phosphate? The Ksp of silver phosphate is 2.8X10^-18

Answer 1

number of moles of AgNO3 = 0.386 *423/1000

                                                  = 0.1633 moles

after mixing total volume = 423 + 459 = 882 mL

concentration of Ag+ = 0.1633/1000*882

                                     = 0.144 M
