Try this first
Chemical changes case 100 electrode-ions. A student predicts electrolysis products. Which option keeps ions and electrodes clear? Focus on that alkalis produce hydroxide ions OH- aqueous solution in The pH scale and neutralisation, not on a neighbouring Unit 4.4 reaction idea.
- A.Chemical changes case 100 electrode-ions: Matches the ion movement to the correct electrode and product for that alkalis produce hydroxide ions OH- aqueous solution
- B.Chemical changes case 100 electrode-ions: Sends positive ions to the positive electrode (The pH scale and neutralisation)
- C.Chemical changes case 100 electrode-ions: Uses electroplating language instead of electrolysis language (that alkalis produce hydroxide ions OH- aqueous solution)
- D.Chemical changes case 100 electrode-ions: Chooses a product without checking the ion discharged (Reactions of acids)
