The reduction potentials for the +2 cations, e.g., 
, of four metals decrease in
the order 
. Which statement(s) is/are true?
(P) 
reduces 
(Q) 
oxidized 
(R) 
oxidizes 
A
only
B
R only
C
P and Q only
D
P and R only
Text Solution
Verified by ExpertsThe correct answer is:
A
According to given data, 
Higher reduction potential
means, more tendency to reduce and lower tendency to oxidize. So, 
. Therefore, 
can't reduce 
and 
can reduced by oxidizing 
. Also, it can oxidize 
. So, only 
is correct.
