Propose a mechanism to separate CuCl2 and NiCl2 dissolved in water.
The solution is aqueous, and I want to separate CuCl2 and NiCl2 into two separate them from each other. Extraction is preferred, but if that does not work, precipitating is also possible.
Homework Answers
Add DMG (dimethyl glyoxime) to the mixture , Ni will precipitate out as red Ni(DMG) complex leaving behind Cu in the solution.
Filter out precipitates of Ni .
Then add NaOH to the filtrate , Cu will precipitate out as white precipitates of Cu(OH)2 . Filter out the Cu precipitates.
Thus Ni and Cu will be separated.

Consider the aqueous solution formed when each of the ionic solids below are dissolved in water. Indicate if the solution will be acidic, basic or neutral. If you indicated that the solution is either acidic or basic, give the pertinent reaction that generates either hydrogen ions H+ or hydroxide ions OH− that involves the appropriate ion. For: MgCl2, KCH3 COO(s), Mg(CN)2(s), NH4 I and LiBr(s)
