The Debye-Hackle limiting law is log_10 gamma = -A |z_+ z_-| I^1/2 Define all the terms in the equation. Use the equation to derive the following expression for the solubility, s, of a salt, MX in terms of its solubility product and the total ionic strength of the solution. 1/2 log_10 K_sp = log_10 S-AI^1/2 the solubility of silver thiocyanate (AgSCN) has been studied in water containing potassium nitrate solutions at 298 K. the solubility of silver thiocyanate was measured to be 1.069 times 10^-6 mole dm^-3 in a solution containing potassium nitrate of unknown concentration. When the concentration of potassium nitrate was halved by dilution with pure water, the solubility of silver thiocyanate was 1.054 times 10^-6 mole dm^-3. Calculate the concentration of the original potassium nitrate solution and the solubility product of silver thiocyanate.
