1.

Consider the following experimental facts. I. When Cl_2 gas is passed into KI solution containingCHCl_3, violet colour appears in CHCl_3 layer. II. When Cl_2 gas is passed into KBr solution containing CHCl_3, orange colour appears in CHCI_3 layer. III. When Brą gas is passed into KI solution containing CHCI_3, violet colour appears in CHCl_3 layer. Select the correct experimental facts.

Answer»

I and II
I and III
II and III
I, II and III

Solution :Oxidisingpower`:F_2gt CI_2gt Br_2gt I_2`
thus `2KI +CI_2to2KCI+I_2"(violetin " CHCI_3)`
`CI_2 `oxidisesKIto `I_2`
thus(I )ISTRUE
`2KBr+CI_2` OXIDISES KBrto `Br_2 `
thus(II )is true

` 2KIBr_2to2KBr+I_2 `
thus(III)is alsotrue
( violetin ` CHCI_3)`
