A metal X displaces nickel from nickel sulphate solution but does not displace manganese from manganese sulphate solution. What is the correct order of their reducing powers?
Text Solution
Verified by ExpertsThe correct answer is:
C
Since X displaces Ni from 
solution, it means X has higher oxidation potential or lower reduction
potential than 
Since X cannot displace Mn from 
solution, it means it has higher reduction potential than 
Lower the reduction potential stronger is the reducing agent hence reducing power Mn > X > Ni.
