(c ) Cl_(2) reacts with NaOH solution to produce sodium chloride and sodium hypochlorite (along with water). (d) Cl_(2) reacts with NaOH solution to produce sodium chloride and sodium chlorate (along with water). (e ) Cl_(2) substitutes hydrogen atoms of a molecule of methane. (f) Cl_(2) reacts with ammonia to form nitrogen and ammonium chloride. (g) Cl_(2) reacts with lime to form bleaching powder. (h) Iodine dissolves freely in water.

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)`.
