I attached the image with the equation, I don't know why it just separates CuSO4 and put Cu²+ + SO²-. Why does it happen? It just ignored the oxidation number of sulfur. Can anyone help me please?

(Image is Zn + CuSO4 :rarrow: Cu + ZnSO4, then Zn0 + Cu2+ + SO42- :rarrow: Cu0 + Zn2+ SO42- in case it breaks, and for search assistance)
You can think of the sulfate ion perhaps as a "super-atom" that doesn't get changed in this reaction, or if you prefer you can split SO42- further up into S6+ + 4O2-. Note that sulfur doesn't always have a -2 oxidation state (and is very unlikely to exist by itself as a 6+ ion.

Have you heard about dissociation of salts?
