Homework Answers
1) Take the unknown solution of cation and add anion W-. If it forms precipitates, then the cation may be A+ or D+ and if it does not precipitate B+ or C+.
2) If it precipitated in 1st step, then take the initial unknown solution of cation and add Z-, and if it precipitates it is A+ and if it does not it is D+.
3) If it did not precipitate in 1st step, then take the initial unknown solution of cation, and add Y-. If it precipitates, then it is B+ and if it did not precipitate then it is C+.
So, like this we can find that which cation is present in the solution.
Add Answer to:
Solutions containing cations A^+, B^+, C^+, and D^+ were mixed with solutions containing anions W^-, X^-,...

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...
