Back (Answer)

Pale yellow gas

Front (Question)

What is the color and state of Chlorine at rtp?

Back (Answer)

Pale green gas

Front (Question)

What is the color and state of Bromine at rtp?

Back (Answer)

Brown-orange liquid

Front (Question)

What is the color and state of Iodine at rtp?

Back (Answer)

Grey solid

Front (Question)

Do boiling points increase or decrease down group 17?

Back (Answer)

Increase

Front (Question)

Does electronegativity increase or decrease down group 17?

Back (Answer)

Decrease

Front (Question)

Why does electronegativity decrease down group 17?

Back (Answer)

Increased shielding. Atoms get larger so the distance between the nucleus and the electrons increases.

Front (Question)

Are hydrogen halides acidic or basic?

Back (Answer)

Acidic

Front (Question)

What is formed when hydrogen halides react with water?

Back (Answer)

Acids and white misty fumes.

#10

Front (Question)

What forms when hydrogen halides react with ammonia gas?

Back (Answer)

White fumes of ammonium halides.

#11

Front (Question)

Does hydrogen halide stability when heated increase or decrease down group 17?

Back (Answer)

Decrease

#12

Front (Question)

What happens when HF and HCL are heated?

Back (Answer)

They are stable and don’t split into H+/F- or Cl- ions.

#13

Front (Question)

What happens when HBr is heated?

Back (Answer)

It partially splits up.

#14

Front (Question)

What happens when HI is heated?

Back (Answer)

It splits up easily.

#15

Front (Question)

What is the chemical test for halides?

Back (Answer)

Silver nitrate solution and then confirm with ammonia.

#16

Front (Question)

What forms when chloride ions are added to HNO3 and AgNO3?

Back (Answer)

White precipitate forms. (silver chloride AgCl)

#17

Front (Question)

What forms when bromide ions are added to HNO3 and AgNO3?

Back (Answer)

Cream precipitate forms. (silver bromide AgBr)

#18

Front (Question)

What forms when iodide ions are added to HNO3 and AgNO3?

Back (Answer)

Yellow precipitate forms. (silver iodide AgI)

#19

Front (Question)

What happens when ammonia solution is added to the silver nitrate tests?

Back (Answer)

Cl - precipitate dissolves in dilute NH3 Br - precipitate dissolves in conc. NH3 I - precipitate is insoluble in NH3

#20

Front (Question)

What is hexane used as?

Back (Answer)

An organic solvent.

#21

Front (Question)

Why is hexane used in displacement reactions?

Back (Answer)

The halogen will dissolve in the hexane and a colored band will appear above the aqueous solution. Color changes are more visible.

#22

Front (Question)

Does reactivity in halogens increase or decrease down group 17?

Back (Answer)

Decrease

#23

Front (Question)

Are halogens more or less oxidising down group 17?

Back (Answer)

Less oxidising.

#24

Front (Question)

What color is the aqueous layer when KBR reacts with chlorine water, bromine water, and iodine solution?

Back (Answer)

Cl2 and Br2 - yellow I2 - brown
