The KspKsp of a salt corresponds to a reaction with the following general format: salt(s)⇌mcation(aq)+nanion(aq)where mm and nn are the coefficients that balance the equation. Equilibrium constants follow the general format of products over reactants (excluding pure liquids and solids) with each species raised to the power of its coefficient in the balanced equation. KspKsp is no exception, so Ksp=[cation]m[anion]nKsp=[cation]m[anion]n Part A If 500.0 mLmL of 0.10 mol L−1 Ca2+mol L−1 Ca2+ is mixed with 500.0 mLmL of 0.10 mol L−1 SO42−mol L−1 SO42−, what mass of calcium sulfate will precipitate?

A chemist at a pharmaceutical company is measuring equilibriumconstants for reactions in which drug candidatemolecules bind to a protein involved in cancer. The drugmolecules bind the protein in a 1:1 ratio to form a drug–proteincomplex. The protein concentration in aqueous solutionat 25 °C is 1.50 x 10-6 M. Drug A is introduced into the proteinsolution at an initial concentration of 2.00 x 10-6 M.Drug B is introduced into a separate, identical protein solutionat an initial concentration of 2.00x 10-6 M. At equilibrium,the drug A–protein solution has an A–protein complexconcentration of 1.00 x 10-6 M, and the drug B solutionhas a B–protein complex concentration of 1.40 x 10-6 M.Calculate the Kc value for the A–protein binding reactionand for the B–protein binding reaction. Assuming that thedrug that binds more strongly will be more effective, whichdrug is the better choice for further research?
In the solubility rules, Ag2CrO4 was listed as an "insoluble" salt.It is actually slightly soluble in an equilibrium reaction:Ag2CrO4 (s) ⇌ 2Ag+ (aq) + CrO42- (aq)The concentration of CrO42- at equilibrium (25oC) is 7.80e-05 M. What is the value of Ksp at this temperature?
In the interface between sediment and water around a deep lake bottom, dissolved oxygen (DO) is usually low. Under such a condition, iron and sulfur typically exist in their reduction forms (i.e. Fe2+ and S2-). Fe2+ and S2- can readily react with each other to produce ferrous sulfide (FeS), which is a black solid substance and finally settles down into the sediments at the lake bottom. The solubility product constant (i.e. equilibrium constant) of FeS is 8 x 10-9. At a chemical equilibrium state, what is the concentration of S2- in the water nearby the sediments if Fe2+ concentration in water is 10 - 4 M.
