🤓 Based on our data, we think this question is relevant for Professor Hempstead's class at York University.
Establish the solubility rules and determine which ion can be used to separate NI2+, Cu2+ and Ag+
Recall that the Solubility Rules are:
•Soluble Ionic Compounds:
▪Group 1A ions (Li+, Na+, K+, etc.) and Ammoniumion (NH4+) are soluble
▪ Nitrates (NO3-), Acetates (CH3COO- or C2H3O2-), and most Perchlorates (ClO4-) are soluble
▪ Cl-, Br-, and I- are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+
▪ Sulfates (SO42-) are soluble except those of Ca2+, Sr2+, Ba2+, Ag+, and Pb2+
Three cations, Ni2+, Cu2+, and Ag+, are separated using two different precipitating agents
Based on Figure 17.22 in the textbook, what two precipitating agents could be used?
