Question

if both I- and Br- are present in test tube then on adding drops of Cl2 water which will give layer test first? explain..

Answer 1

I- forms a layer because order of reactivity is
I>br>cl>f

Answer 2

Hey dear,

● Answer -
I- will give layer test first

● Explaination -
- Ractivity of halogen acids increases down the group in periodic table
HI > HBr > HCl > HF(unreactive)
- In solution halogen acids dissociative to H+ and X-.
- Therefore, when I- and Br- ions are present in solution, I- will react faster with Cl2 water.
- Therefore, I- will give layer test first.

Hope this helps you...
