Use the Refereaces to ancess lnportant valees if weeded for this qeestion In the laboratory you are given the task of separating Ba2. and Co 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" Y or N Formula of Precipitate if CO Submit Answer 11. Separate lons: Choose Reagents: This is group atempt 4 of 5 Autosaved at 11:44 AM

Explanation / Answer

Y or N    reagent         formula of precipitate if yes
Y         Na2S             CoS
N         NaCl           
N         K2Co3            BaCo3, CoCO3

Co^2+ (aq) + Na2S -----------> CoS(s) + 2Na^+ (aq)
Co^2+ (aq) + 2NaCl ---------> CoCl2(aq) + 2Na^+ (aq)
Ba^2+ (aq) + 2NaCl ---------> BaCl2(s) + 2Na^+ (aq)
