Consider three P, Q, R, salts among them P and Q salts have different cations annd also have different coloured polyatomic anion due to charge transfer phenomenon while P and R salts have same cation but have different anions. Salts R decomposes into an acidic gas an a basic gas.
Q. If salt Q underrgoes redox reaction with `H_(2)S` in acidic medium then which of the following speies can not be possible product?

Options

A. `MnO_(4)^(2-)(aq.)`
B. `S`
C. `MnO_(2)`
D. Both (a) and (c)

Answer

D

Explanation

`underset((O.A." "MnO_(4)^(-)))('Q'" salt")+underset((R.A.))(H_(2)S) overset(H^(+))to S+Mn^(2+)(aq.)`
