Question

The process that you see is used for the purification of copper. A thin plate of pure copper and a thick rod of impure copper are used as electrodes. Copper from the impure rod is sought to be transferred to the thin copper plate. Which electrode should be attached to the positive terminal of the battery and why?

Answer 1

Charge is that the basic property of forms of matter that exhibit static attraction or repulsion within the presence of different matters. Electric charge may be a characteristic property of the many subatomic particles. For understanding this question we must have to know the types of charges.

Complete step-by-step answer:
Electric charge is the basic property of matter that causes it to experience a force once kept in an electrical or field. An electric charge is related to an electrical field and therefore the moving electrical phenomenon generates a field.
The combination of electrical and magnetic fields is understood because of the electromagnetic field. Interaction of the charges generates an electromagnetic force that is the foundation of Physics.
By the charge definition we all know that charge is of 2 types; Positive and negative, ordinarily carried by charge carriers protons and electrons. The subatomic particles or the particles of matter have varied charges like protons are positively charged and electrons are negatively charged and neutrons have zero charges.
Copper is positively charged therefore it'll get drawn to the negative conductor as a result of positive charges attracting negative charges. As copper ions are deposited on the copper plate the skinny copper plate should be connected to the negative terminal of the battery hence the impure copper rod gets connected to the battery having a positive terminal.
The various properties of charge embrace the following: Additive of electrical Charge Conservation of electrical Charge Quantization of electrical Charge In any isolated system, the electrical phenomenon is preserved and constant.

Notes: Preparation of the copper: Copper is refined by electrolysis. Electricity is passed through solutions containing copper compounds, like copper (II) sulfate. The anode (positive conductor) is created from impure copper and therefore the cathode (negative electrode) is created from pure copper. Pure copper forms on the cathode.
