Question
When sodium hydroxide solution is electrolysed:(a) hydrogen is discharged at cathode(b) hydrogen is discharged at anode(c) sodium is liberated at anode(d) no hydrogen is liberated
Step 1
This can be represented by the following half-reaction: \[2H_2O(l) + 2e^- \rightarrow H_2(g) + 2OH^-(aq)\] Show more…
