Answer» Solution :(a) In presence of moisture, chlorine acts as a good bleaching agent. (B) A mixture of `H_(2)` and `Cl_(2)` explodes on exposure to direct sunlight. (c ) `Cl_(2)` reacts with `NaOH` solution to produce `NaCl` , sodium hypochlorite and `H_(2)O` in cold and dilute conditions. (d) When `NaOH` solution is hot and concentrated it reacts with `Cl_(2)` to produce sodium chloride, sodium chlorate and water. (e) In diffused sunlight, `Cl_(2)` substitutes hydrogen atoms of a molecule of methane. (f) when `NH_(3)` is in excess, it reacts with `Cl_(2)` to form `N_(2)` and `NH_(4)Cl`. (G) On passing `Cl_(2)` over dry slaked lime, bleaching POWDER is formed. (h) Iodine dissolves freely in water in presence of `KI`. (i) In dry conditions, `Cl_(2)` FORMS an addition product with `SO_(2)`. |
