Confusing Ions in Aqueous Solutions
Students often forget that aqueous solutions contain not only ions from the ionic compound but also hydrogen ions and hydroxide ions from water.
To fix this, remember to include all types of ions present in the solution when describing aqueous electrolysis, specifically noting the contribution of water.
