Im really struggling with chemistry at the moment, and all of our teachers are just placing practicals upon us with an average of 2 days notice. I have been gien the context of an experiment whch is
mr [Personal details removed by Moderator] wants a pure sound for his headphones- it is something to do with electrolysis but I do not understan why.. I also need to research a method and hypothisis for it and im struggling because i dont understand
really relally appreciate yr help guys

Is it an ISA? Your teacher has to set a context for the investigation. Maybe they're thinking of electroplating copper onto the headphone plug to make a good electrical contact, or electroplating copper to get pure copper for the wires? It's difficult to know from what you say - you really do need to ask your teacher for help to get started.
You have to develop your own hypothesis, and research a possible method to investigate it. Once you've done that, you need to write a detailed plan for this method.
A typical investigation often used in schools is to see what affects the amount of copper that forms on the negative electrode. But again it's difficult to be sure from what you say, and I think you should ask.
