1. The diagram below shows the electrolysis of concentrated aqueous potassium chloride using platinum electrodes. Which of the following statements is TRUE regarding the electrolysis of concentrated aqueous potassium chloride?
H₂O is reduced at the cathode due to its more negative E⁰ value than K⁺.
Cl⁻ is oxidised at the anode due to its more positive E⁰ value than H₂O.
Cl⁻ ions are oxidised at anode due to higher concentration.
Platinum is an active electrode.

2. The standard reduction electrode potential for several half-reactions at 298 K are shown below. Which of the following species is the strongest oxidising agent?

X⁻

Y³⁺

Z

X₂

Answer explanation

strongest oxidising agent -> undergo reduction (gain electron, +SRP value) -> species who gain electron (look at reactant side)
