Question

Among the following  X compounds are exclusive oxidising agents  y compounds are exclusive reducing agents Z can function as both as oxidising and reducing agents then the value of X+Y-Z

H2S,NH3,SO2 ,HNO3,HNO2,KMnO4,K2Cr2O7,O3,H2O2,PbO2​

Answer 1

Answer:2

Explanation:

Here their minimum oxidation state compounds acts as a reducing agent and maximum oxidation state compounds acts as oxidising agent any between oxidation numbers acts as both oxidising any reducing agent

Here H2S NH3 has min oxidation state, so there are.reducing agent

Y=2

HNO3 KMnO4 K2Cr2O7 PbO2 are having Max oxidation state, so there are oxidising agent

Hence X=4

Remaining compounds are acts as both oxidising and reducing agent ,so Z=4

X+Y-Z=2
