What are the patterns and trends of chemical properties observed when testing reactivity of halogens?
I missed a lab lesson last week and was wondering if anyone could help.
Basically I need to know what happens when you mix KCl, KBr, and KI with a Cl, Br, and I solution.
So KCl with bromine solution, then KCl with Iodine solution etc.
if anyone can help it’d be much appreciated.
1. Which halides will be replaced by Cl2? by Br2? by I2?
Reactivity DECREASES down group VII F-> Cl-> Br -> I
So fluorine will displace all halides below it Cl, Br,I, then Cl2 will displace Br & I and so on
2. How can Cl- be distinguised from Br- and I-? Add to silver nitrate soln . Cl gives white AgCl precipitate, AgBr is cream, AgI yellow
3. Explain the formation of two distinct liquid layers when hexane is added to the water solutions. Hexane is IMMISCIBLE with water because it is totally non polar and won’t mix. Br and I can be detected by shaking results of 1] with organic solvent like this and give different colours in many solvents
Mainly copied and pasted from near identical question this week.
