Using the data below, arrange the four salts in order of increasing molar solubility in pure water at 25 °C. Mg(OH)2\mathrm{Mg(OH)_2}: Ksp=1.2×10−11K_{sp}=1.2\times10^{-11} BaSO4\mathrm{BaSO_4}: Ksp=1.1×10−10K_{sp}=1.1\times10^{-10} Ag2SO4\mathrm{Ag_2SO_4}: Ksp=1.2×10−5K_{sp}=1.2\times10^{-5} NaNO3\mathrm{NaNO_3}: Ksp>1K_{sp}>1 (readily soluble) a) Ag2SO4\mathrm{Ag_2SO_4} < BaSO4\mathrm{BaSO_4} < Mg(OH)2\mathrm{Mg(OH)_2} < NaNO3\mathrm{NaNO_3} b) Mg(OH)2\mathrm{Mg(OH)_2} < Ag2SO4\mathrm{Ag_2SO_4} < BaSO4\mathrm{BaSO_4} < NaNO3\mathrm{NaNO_3} c) BaSO4\mathrm{BaSO_4} < Mg(OH)2\mathrm{Mg(OH)_2} < Ag2SO4\mathrm{Ag_2SO_4} < NaNO3\mathrm{NaNO_3} d) Mg(OH)2\mathrm{Mg(OH)_2} < BaSO4\mathrm{BaSO_4} < Ag2SO4\mathrm{Ag_2SO_4} < NaNO3\mathrm{NaNO_3}
