Homework Answers
1) Case 1 when Q > Ksp
The solution is supersaturated, thus concentrations of ions will
be greater than equilibrium concentrations. So, reaction will
proceed in backward direction to reach equilibrium. And hence
precipitation will occur.
2) Case 2 when Q < Ksp
The solution is unsaturated, thus the concentration of ions will be less than equilibrium concentrations. So, the reaction will proceed in forward direction to reach equilibrium and hence more solid can be dissolved.
3) Case 3 when Q = Ksp
The solution is saturated. Thus the solution is at equilibrium
and ion concentrations are equilibrium concentrations. So, no
more solid can be dissolved further.

if you can use a keyboard for writing the answer I will be thankful. Q) Consider the following compounds: methanol, ethoxyethane, ethanol, butane. Rank these compounds from least to most soluble in water. Be sure to evaluate the enthalpic changes in addition to intermolecular forces as you consider the compounds. Indicate a 'plan' on how you intend to solve the problem. You can use arrows Show the step by step solution of the problem. For example, if you have a...
