How to solve questions on electrolysis
Answers
Answer:
learn definition and what things are needed : anode ,cathode ,Acidic substance , atoms
Answer: To solve a question on electrolysis we need to know about the Anode, Cathode, Electrolyte and about metals and non-metals, also about ionic substances, molten substances, concentrated and dilute solutions.
Example question,
Where do the Sodium go during the electrolysis of Molten Sodium Chloride, to the anode or cathode?
Answer; First you have to know the ions present, [ Na+ ions and Cl- ions]
then you have to know to what electrode does the negative ions attract and where does the positive ions attract.
Ions attract to opposite charged electrodes.
So Na+ ions go to Cathode and Cl- ions go to the anode.
So the answer is that sodium goes to the Cathode.
Hopefully u can learn something important don't forget to rate me the brainiest if the answer helped u.
