Back (Answer)

Br- and I-

#2
Front (Question)

what will Br2 displace?

Back (Answer)

I- only

#3
Front (Question)

what will I2 displace?

Back (Answer)

I2 will not displce any halide ions

#4
Front (Question)

observation for mixing aqueous Cl2 and aqueous KBr

Back (Answer)

orange solution formed with solvent

#5
Front (Question)

observation for mixing Cl2 and KI (both aqueous)

Back (Answer)

pink solution formed with solvent

#6
Front (Question)

observation for mixing Br2 and KI (both aqueous)

Back (Answer)

pink solution formed with solvent

#7
Front (Question)

testing for halides steps

Back (Answer)

-add dilute HNO3 to each test tube of unknown aqueous halide -add aqueous silver nitrate (AgNO3) F- gives no precipitate Cl- gives white ppt Br- gives cream ppt I- gives yellow ppt

#8
Front (Question)

if adding silver nitrate gives ppts which are hard to distinguish, what further steps and observations should be taken?

Back (Answer)

• add dilute ammonia to each test tube • Cl- ppt dissolves in dilute ammonia • Br- ppt dissolves in conc. ammoina • I- is insoluble in dilute and conc. ammonia, so no change.
