Question
using solubility rules and Ksp indicate how you would sperate the following groups of ions. (can write it out (see example) or use flow chart) please help me!
1. Pb2+, Mn2+, Cr3+, K+
2. NH4, Ba2+, Sn2+, Cd2+
3. Cu2+, Ni2+, Cu2+, Ag+
4. Pb2+, Ag+, Fe3+, Ni2+, Al3+
5. Fe3+, Ca2+, Cu+, Be2+
example: Cu2+, Ag+, Ca2+
Treat sample with dilute HCL to ppt AgCl; centifuge out solid. treat supernatan with acidic H2S to ppt CuS, centerfuge out solid. what remains is Ca2+ that can ppt adding NH4CO3(aq) to the supernatant form CaCO3 solid.
Explanation / Answer
Q1.
PB+2 < Mn+2 < Cr3 < K+
Q2.
Cd+2 < Sn+2 < Ba+2 < NH4+
Q3.
Ag+ < Cu+2 < Ni+2
Q4.
Ag+ < Pb+2 < Fe+3 < Ni+2 < Al3+
Q5
Ag+ < Mg+2 < Cu+ < Ca+2
