Identifying Unknown Solutions Set 3

This is Set 3 of three similar videos, labelled Set 2, Set 3 and Set 4 (There is no set 1). The point of the exercise is, given 4 solutions of ionic compounds, to identify which is which based on ion colours and solubility rules. The video only shows the observations, without explanation. It is intended either for review after students have completed the lab in class, or as a virtual lab experience for students working remotely.
The 4 solutions in set 3, in no particular order, are
copper(II) sulfate
sodium phosphate
sodium chloride
zinc nitrate
As for which is which, well, figuring that out is the point of the exercise.
