- Question: How do you expect solubility of potassium bitartrate to vary between solutions with and without KNO3?(Q46) Given that the molar solubility of copper (1) chloride (99.00 g/mol) at 25°C is 4.15 x 10-4 mol/L, it follows that at equilibrium: O 41.1 mg of CuCl will exist in one liter of solution as a precipitate 41.1 mg of CuCl will be dissolved in one liter of solution O 41.1 mg of precipitate and 41.1 mg of dissolved ions will be present in one liter of solution O Increasing the temperature would have no effect on solubiility O Diluting the solution would cause precipitation to beginWhat would be the learning objective in an experiment of the determination of the Ksp of a slightly soluble compound?
