Chemistry - Oxidising Agents

An oxidising agent is reduced in the process

Acidified potassium manganate (VII)

purple to colourless

ACM 7

purple Mno4-1 changes to colourless Mn²+ ion

Acidified potassium dichromate

orange to green

ACD 6

orange Cr2O7^-2 changes to green Cr³+ ion

Iron (III) salts

yellow to pale green

Fe³+ salts

Fe³ ion changes to pale green Fe²+ ion

Conc H2SO4

pungent gas produced

Conc H2SO4 reasoning

Sulfur dioxide being produced

Nitric Acid

brown gas produced

NA reasoning

nitrogen dioxide is produced

Oxygen gas

is an oxidsing agent
