A saturated solution is formed when a salt is added to water until equilibrium is established between the undissolved salt and its ions in solution. This process can be represented by the equation: Ag2Cr)7(s) ⇌ 2Ag+ (aq) + Cr2O7^2- (aq)
At a particular temperature, the concentration of the silver ions in a saturated solution of silver dichromate is 7.24E-3 M. What is the equilibrium constant, Ksp, for this salt at this particular temperature?
