An unknown salt consists of two types of cations and one type of anion
An unknown salt consists of two types of cations and one type of anion. The possible anions include chloride, Cl-, carbonate, CO32-, sulfate, SO42-. The possible cations include Group 1A cations, K+ and Na+, and Group 2A cations, Ca2+ and Sr2+.a) After dissolving the unknown in 20 mL of DI water, you add 0.5 mL of 0.05 M AgNO3 and observe a precipitate. What are the possible precipitates that are formed? Write the net ionic equations for the reactions. b) When...
