Question

Which of the following can cause a flow of current through an electrolyte?
a. Movement of nucleus
b. Movement of electrons
c. Movement of protons
d. Movement of ions​

Answer 1

The movement of ions causes the flow of current through an electrolyte.

• An electrolyte is a salt that when added to water conducts electricity as it acts as a charge carrier in form of an ion.

• On dissociation, it releases a positively charged ion which is called a cation, and a negatively charged ion which is called an anion.

• Positive charged-ion moves towards the cathode ( negatively charged electrode)  and negative charged-ion moves towards the anode(positively charged electrode) and conduct electricity in the solution.
