Consider the b.pr. of `Br_2` and ICl. The b.pt. of `Br_2`

The molecular size of Icl and Br_(2) is approximately same, but b.p. of Icl is about 40^(@)C higher than that of Br_(2) . It is because :

Consider the reaction: (T = 298 K) Cl_2 (g) + 2 Br^(-) (aq) rarr 2 Cl^(-) (aq) + Br_2 (aq.) The emf of he cell, when [Cl^(-) = (Br_2] = [Br^(-) ] = 0.01M and Cl_2 gas is at 1 atm pressure, will be : ( E^@ for the above reaction is = 29 volt ).

Molecular size of ICI and Br_2 is nearly same but b.pt. of ICI is about 40^@ higher than BR_2 . This is due to :

Consider the following reaction CH_3-CH=CH_2overset(Br_2//NaCl)rarr Product of the reaction will be

Consider the following reaction CH_3-CH=CH_2overset(Br_2//NaCl)rarr Product of the reaction will be

When BrO_3^- iron reacts with Br^- in acid medium, Br_2 is liberated. The equivalent mass of Br_2 in this reaction is :

When BrO_3^- iron reacts with Br^- in acid medium, Br_2 is liberated. The equivalent mass of Br_2 in this reaction is :
