10.2- THE CHEMICAL REACTIONS OF THE HALOGENS

Question 1

How do halogens usually react by?

Answer 1

react by gaining electrons to become negative ions

Question 2

What charge would the halogens have when they gain the electrons?

Answer 2

charge of -1

Question 3

What type of reaction is it when the halogen reacts by gaining electrons?

Answer 3

redox reactions

Question 4

Are the halogens reducing or oxidising agents?

Answer 4

oxidising agents

Question 5

Are halogens reduced or oxidised?

Answer 5

reduced

Question 6

How does the oxidising ability change going up the group?

Answer 6

oxidising ability of halogens increases going up the group

Question 7

What is one of the most powerful oxidising agents known?

Answer 7

fluorine

Question 8

What happens when a halogen reacts with a hydrogen halide in a solution?

Answer 8

halide in compound will be displaced by more reactive halogen but not less reactive one

Question 9

What is it called when the halide in a compound is displaced by a more reactive halogen?

Answer 9

displacement reaction

Question 10

Why can you not investigate fluorine in an aqueous solution?

Answer 10

because it reacts with water
