Show hintHide hint
Think about how oxidation and reduction are represented separately.
Question 2.
Why do we balance H⁺ ions in acidic conditions?
Show hintHide hint
Look at how hydrogen emerges from water, and what is used to balance it.
3Question 3.
What does oxidation refer to in a redox reaction?
- Gain of electrons
- Loss of electrons
- No change
Show hintHide hint
Remember the acronym OIL RIG.
