Write a solubility product constant expression, K_sp, for an equilibrium in a saturated aqueous solution of the slightly soluble salts Magnesium fluoride, MgF_2 Zinc phosphate, Zn_3(PO_4)_2 Chromium(II) hydroxide, Cr(OH)_3 Strontinum sulfate, SrSO_4. Calculate the solubility in g/L for calcium carbonate, CaCO_3, in pure water given the K_sp = 2.8 times 10^-9. Calculate the solubility in g/L for CaCO_3, in 0.050 M Na_2CO_3.
QUESTION 4 If you take a 171 mL of a 1.4 M NaCl solution and dilute it to 500 mL, what is the molarity of the final solution? Enter the numerical answer in decimal notation QUESTION 10 Information - Colligative Properties Colligative properties of solutions are those properties which depend only on the number of dissolved solute particles in solution not the chemical properties of the solute. For example when a solute is dissolved in a solvent, vapor pressure depression...
