Very dilute sodium chloride solution is electrolysed. Which test provides a positive result for the gas produced at the anode?
Question
Solution 1
The gas produced at the anode during the electrolysis of a very dilute sodium chloride solution is chlorine.
To test for chlorine gas, you can use damp litmus paper. Chlorine gas will bleach the litmus paper, turning it white. This is a positive result for the presence of chlorine gas.
