U'se the Reterences te access important valoes if eeded for this question In the laboratory you are given the task of separating Ca and Cu ions in aqueous solution. For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formala of the precipitate. If it cannot, type No" YorN Reagent Formula of Precipitate if YES Na CO KOH Na SO4 Submit Answer ns Choose Reagents This is group attempt 2 of 5 Autosaved at 2 49 PMExplanation / Answer
+
BOTH GIVES SAME COLOR
Ca2+ + KOH = Ca(OH)2+ 2K+
MILKY COLOR
SOLUTION
Cu2+ + KOH = Cu(OH) + 2K+
PALE BLUE
COLOR PPT
Ca+2+ Na2SO4 = CaSO4 +2Na+
white
Cu+2 + Na2SO4 = CuSO4 + 2Na+
