Chemical changes case 101 ph-precision. A student explains pH or neutralisation. Which option avoids vague wording? Focus on that oxidation happens the anode because negative ions in Representation of reactions at electrodes as half equations (HT only), not on a neighbouring Unit 4.4 reaction idea.
- A.Chemical changes case 101 ph-precision: Links pH or neutralisation to hydrogen ions, hydroxide ions or water formation for that oxidation happens the anode because negative ions
- B.Chemical changes case 101 ph-precision: Says strong acid means concentrated acid (Representation of reactions at electrodes as half equations (HT only))
- C.Chemical changes case 101 ph-precision: Says neutralisation only means the mixture becomes harmless (that oxidation happens the anode because negative ions)
- D.Chemical changes case 101 ph-precision: Uses pH numbers without linking them to acidity or alkalinity (Electrolysis)
