Question

A solution containing hydroxide ions will react with chlorine gas to produce chloride ions, gaseous oxygen, and water.

Cl2(g) + 2e- → 2Cl-(aq)

O2(g) + 2H2O(l) + 4e- → 4OH-(aq)



Write a balanced net ionic equation for this reaction.


I'm very lost honestly, thank you for your help

Answer 1

Why confused. The problem tells you to take the Cl2 reactin as written and use the other other one reversed (because you want to add OH^- to it) and add them together. Keep the electrons equal by multiplying the 2e x 2 and the 4e by 1
