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...

It is important to think through the reactions that are occurring (or not occurring) and determine how you can rule out the presence of a certain metal ion or how you can posi- tively identify its presence. Use the Solubility Table 1 and Appendix 1 of this manual to understand the precipitation réactions that are observed. You need to consider both the anion and the cation that react to form a given precipitate. The color and the general ap- pearance...

To determine the salt formed during a neutralization reaction, combine the anion formed by the dissociation of the acid and the cation formed by the dissociation of the base in a ratio that results in a neutral, ionic compound. For example, if you have a cation with a 1+ charge and an anion with a 2- charge, you will need two cations to balance the charge. [(1+ charge on cation)(2)]+[2 - charge on anion)(1)] = (+2) + (-2) = 0...
