Q

Which Halogen is the best reducing agent and why?

A

Iodine because atoms get larger which increases the shielding and outer electrons are more easily lost

17
Q

Which halogen is the best oxidising agent?

A

Fluorine

18
Q

What are the products and observations of H2SO4 and Cl-?

A

HCl
White Steamy fumes

19
Q

What is produced when NaBr reacts with H2SO4?

A

HBr= White steamy fumes
SO2= Colourless gas
Br2

20
Q

What are the products when NaI + H2SO4?

A
  • HI- White steamy fumes
  • SO2- Colourless gas
  • I2
  • Sulfur- Yellow solid
    -H2S- Choking gas
21
Q

What is disproportionation?

A

When an element oxidises and reduces at the same time
E.g Cl and H2O
