Question

Please help me c: What happens when Zn is combined with CuCl2, MgCl2 and FeCl3. I need observations for each...

Answer 1

are you combining solutions of these?

Answer 2

Yes I am, the procedure is to combine Zn with each solution and record what happens

Answer 3

I would start by looking at their Ksp's which will determine if they're all soluble. Check for the combinations of the anions in the compounds with Zn. This can give you information about a precipitate forming.

Also, most (if not all) Zn^2+ containing compounds are colourless because it has a full d orbital (so no electrons are able to transition in wavelengths that correspond to the visible spectrum). Do you know what colours Cu, Mg, Iron compounds are?

Answer 4

The 1st solution is blue the other 2 are colorless

Answer 5

are you sure about iron?

Answer 6

it s metal displacement reaction i think u have too do it based on their redox potential

Answer 7

can addition of Zn replaces Cu from CuCl2, MgCl2 and FeCl3 is the question i

Answer 8

FeCl3 is dark yellow color
