Question 17

Explain how hydrogen is produced during electrolysis of water?

Answer 17

1. An electrical current is put through the water
2. This splits water into 2H+ and 02- ions
   3.The negatives are attracted to the positive anode
3. At the anode/ cathode either oxidisation or reduction happens
   5.Looses electrons = oxidation
   Gains electrons = reduction
4. Eg: 2 oxygen - becomes O2 +2e-
