Question 15
ElectrolysisIn the electrolysis of aqueous solution of K2SO4 in the above cell, which species migrate to the anode?

- A.SO42− and OH−
- B.K+ and SO42−
- C.OH− and H3O+
- D.H3O+ and K+.
Show the answer and explanation
Answer: A (SO42− and OH−)
Explanation
The anode is positive, so the negative ions move to it. In K2SO4 solution these are SO42− and OH−.
