- The conspicuous change observed is the coagulation of the sol, which may lead to the formation of a precipitate or a change in the appearance of the solution, such as cloudiness or a change in color. Final Statement:When a solution of NaCl is added to a sol of hydrated ferric oxide,...
It can also be prepared by reacting magnesite (magnesium carbonate, MgCO3) or magnesia (oxide, MgO) with sulfuric acid. Another possible method is to treat seawater or magnesium-containing industrial wastes so as to precipitate magnesium hydroxide and react the precipitate with sulfuric acid....
What type of reaction produces a precipitate? The solubility of CdCO_3(s) in 1.00 M KI(aq) is 1.2 x 10^{-3} mol/L. Given that K_sp of CdCO_3 is 5.2 x 10^{-12}, what is K_f for [CdI_4]^{2-}? What is the molar solubility of CaF_2 in a 0.100-M solution of HF?
