  • Solvent Extraction Of Zinc From An Acidic Copper Ron Solution

Redox reaction from dissolving zinc in copper sulfate

You get a redox reaction where the copper takes electrons from the zinc So it becomes neutral solid copper And the zinc loses those electrons to the copper And so those become zinc cations Or you could think of it as zinc sulfate dissolved in the aqueous solution So let me write that down Zinc sulfate and that has a negative charge still and it is in an aqueous solution So what will this actually look like?
