Consider the dissolution of ab(s): ab(s)⇌a+(aq)+b−(aq)le châtelier's principle tells us that an increase in either [a+] or [b−] will shift this equilibrium to the left, reducing the solubility of ab. in other words, ab is more soluble in pure water than in a solution that already contains a+ or b− ions. this is an example of the common-ion effect. the generic metal hydroxide m(oh)2 has ksp = 1.05×10−18. (note: in this particular problem, because of the magnitude of the ksp and the stoichiometry of the compound, the contribution of oh− from water can be ignored. however, this may not always be the case.)what is the solubility of m(oh)2 in pure water?

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
