Chemistry unit 2

HideShow resource information
describe group 2
halides and are reactive producing colour vapour
1 of 7
boilong point
has high boilong point as you go down the group as it needs to break the van der waals forces
2 of 7
displacement reaction
haloides will react with metal halides, a halide will be replaced by more reactive halide
3 of 7
what happens to the reactiving up the group
the reativity increases as you go up the group
4 of 7
tresting for halides
add nitric acid then acidified silver nitrate, chlorine is white bromine is cream idodine is yelloe
5 of 7
how to test for crabonates and what is observed
test add aci and bubble through limeatwer, gas is produced and goes cloudy
6 of 7
test for sulftaes and what is obsereved
add dilute hydrochloric acid to barium chloride, white preciptate of barium suldie
