The correct options are
A H2SO4 can be used for drying H2S gas.
C H2S is a better reducing agent than water.
D H2S can form coloured precipitate's with metal ions.
H2SO4 can be used for drying H2S gas.
H2S is a better reducing agent than water because O−H bond is stronger than S−H H2S can donate H+ in a better way than H2O
H2S can form coloured precipitate with metal ions.
