Problem

Which gives the more concentrated solution,  (a) KNO3 in H2O or (b) KNO3 in carbon tetrachloride (CCl4)? Explain.

Solution
  • KNO3 or potassium nitrate is an ionic molecule that dissociates as Kand NO3-

  • Problem is asking which solvent will produce more concentration of Kand NO3-. Recall that ionic compounds are highly soluble to polar solvents
