Question

Standard Reduction potential of three imaginary elements are given:
$X=2.80V,Y=0.35V,Z=0.01V$
Which of the following is true?

• A. $X$ can oxidise $Y$
• B. $Y$ can oxidise $X$
• C. $Z$ and oxidise $X$
• D. None of the above.

Answer 1

The correct option is A $X$ can oxidise $Y$

The more the reduction potential of an element more is the oxidising power. Hence, it is a more effective oxidising agent. Less the reduction potential less is the oxidising power. Hence, it is a weak oxidising agent or strong reducing agent.

So, from the given data:
$\Rightarrow$ Z is the strongest reducing agent among these.
$\Rightarrow$ X is the strongest oxidising agent among these.

Oxydising power order:
$X>Y>Z$
$\therefore$ (a) is the correct choice.
