Why dilute copper sulfate with vinegar for electroplating?
what effect does vinegar have on electroplating [since most experiments ask us to dilute copper(II) sulphate with vinegar?Charlene

It's hard to guess what the textbook author may have had in mind, especially when we haven't seen the experiment, but vinegar is a very mild acid and will help the copper stay dissolved and help provide conductivity as the copper sulphate is diluted.

It would normally be used because it is significantly safer for students to use than sulfuric acid. A plus is that it will form a copper acetate complex and tend to give you a tiny bit more uniform plating in the low current density areas.James Watts
