S(1): 2Se(2)Cl(2)rarr SeCl(4)+3Se S(2)...

`S_(1): 2Se_(2)Cl_(2)rarr SeCl_(4)+3Se`
`S_(2)` : Dioxides like `MnO_(2), PbO_(2)` do not form `H_(2)O_(2)` with dilute acids but they evolve oxygen with concentrated `H_(2)SO_(4)`.
`S_(3)` : Sodium thiosulphate with `FeCl_(3)` solution develops a pink or violet colour which soon vanishes.
`S_(4)` : White precipitate of `PbS_(2)O_(3)` get soluble when boiled with water.
