1.1The Ksp of Ca3 (PO4 ) 2 is 1.3 × 10−26 . Estimate the solubility of this salt in units of g. L −1 . You must show any reaction equation(s) that you may think are necessary. 1.2 If a sample of solid Ca3(PO4)2 is stirred into exactly one litre of a 0.550M solution of Na3PO4, how will the solubility of the salt compare with the answer that you have obtained in question 1.1? Explain you answer in a short sentence.
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.

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?
