A transition metal

\mathrm{M}

can exist in two oxidation states +1 and +2 . It forms a sulphide whose experimental formula is given by

\mathrm{M}_{\mathrm{x}} \mathrm{S}

where

2 > x > 1

. Then the ratio of metal ion in +1 state to those in +2 state in sulphide is given by

View answer and explanation

Correct option: B

\frac{2(x-1)}{2-x}

Option B (

\frac{{2(x-1)}}{{2-x}}

) is correct because it represents the ratio of M+1 to M+2 ions based on the given formula MxS and charge balance.
