Chemical changes case 010 acid-base-boundary. A student sorts acid, alkali and base statements. Which option keeps the terms distinct? Focus on the negative electrode the cathode in The process of electrolysis, not on a neighbouring Unit 4.4 reaction idea.

The correct option is Chemical changes case 010 acid-base-boundary: Keeps the acid-base distinction tied to the named substance for the negative electrode the cathode.

The correct option is Chemical changes case 010 acid-base-boundary: Keeps the acid-base distinction tied to the named substance for the negative electrode the cathode. It is correct because it directly supports the approved learning objective to identify the negative electrode as the cathode in The process of electrolysis. The other options are incorrect because they blur a Unit 4.4 concept boundary: acid versus alkali versus base, oxidation versus reduction, displacement versus reduction, electrolysis versus electroplating, anode versus cathode, positive versus negative ions, oxidation state versus ionic charge, or strong acid versus concentrated acid.
