What chemical is used to separate Ca2+ and Ba2+ ions from a solution containing Ca2+, Ba2+, NH4+, and K+ ions? What are the p

Answer 1

Answer #1

Ammonium carbonate((NH4)2CO3) is used in a slightly basic medium to separate Ca2+ and Ba2+ ions from a solution containing Ca2+, Ba2+, NH4+ and K+

Ba2+ and Ca2+ forms insoluble carbonates (CaCO3 and BaCO3 percipitate) in slightly basic medium

Ba2+ + (NH4)2CO3 → BaCO3 (ppt.)

Ca2+ + (NH4)2CO3 → CaCO 3 (ppt.)

In many chemical reactions of two or more compounds, ions are present in the solution that do not participate in the reaction. These ions, known as spectator ions, can be removed from the chemical equation describing the reaction. A chemical equation that has the spectator ions removed is known as a net ionic equation. Reactions between ionic compounds often result in the precipitation of an insoluble compound. Spectator ions and precipitation products of a chemical reaction can be predicted by...

Qualitative Analysis of Metal Cations Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics. One such scheme is shown in the flow diagram. Some ions that are soluble in all of the test solutions can still be identified based on flame tests. Certain ions impart characteristic color to the flame.Part AA solution contains some or all of the ions Cu2+, Al3+, K+, Ca2+, Ba2+, Pb2+, and NH4+. The following tests were performed, in...
