OXIDATION NO

QuestionAnswer
OXIDATION EXAMPLE... BURNING FUELS RUSTING IRON, BLEACHING OF DYES.
EXTRACTION OF METAL FORM ITS ARE IS ... REDUCTION
WHEN METHANE BURN... O2- REDUCED AND METHANE IS OXIDISED.
REMOVAL OF OXYGEN IN A SPECIES. ... IS REDUCTION.
FE2O3 + 3CO  2FE + 3CO2 EXAMPLE OF REDOX IN BLAST FURNACE... EXTRACTION OF IRON. IRON OXIDE LOSES OXYGEN AND IS REDUCED, C0 GAIN OXYGEN AND IS OXIDISED.
GAIN OF OXYGEN... OXIDATION. LOSS OF ELECTRON
CHLORINE GAS IS BUBBLED INTO AQUEOUS HYDROGEN SULPHIDE... THE HYDROGEN SUPHIDE IS OXIDISED TO SULFUR BY REMOVAL OF HYDROGEN. THE CHLORINE IS REDUCED HCL BY ADDING HYDROGEN. H2S + CL2 2HCL.
GAIN OF HYDROGEN ... REDUTION
LOSS OF HYDROGEN ... OXIDATION
THE COMBUSTION OF MAGNESIUM IN OXYGEN ... IS OXIDATION. MG + ½ O2  MGO.
MAGNESIUM HAS ELECTRON CONFIGURATION [NE] 3S2 ... EACH MAGNESIUM ATOM LOSES ITS OUTER 2 ELECTRONS BECOMING (3S0) THE OXYGEN GAINS THE ELECTRONS RESULTS IN FORMATION OF MG2+ AND O2- IONS. O + 2E- O2-.
MAGNESIUM IS OXIDISED ... COZ HAS LOST ELECTRONS – CL AND O ARE REDUCED. OILRIG.
REDUCTION OF IRON OXIDE IN BLAST FURNACE ... FE3+ + 3E-  FE.
WHEN CL (G) IS PASSED OVER KBR ... THE BROMIDE IONS LOSES ELECTRONS AND BECOME BROMINE. THE CHLORINE MOLECULES GAINS THE ELECTRONS (REDUCED) BECOMES CHLORIDE IONS. BROMIDE IONS OXIDISED TO BROMINE, CHLORINE REDUCED TO CHLORINE IONS.
OXIDISING AND REDUCING AGENTS CHLORINE SEEN AS OXIDISING AGENT. THE BROMIDE IONS HAVE REDUCED THE CHLORINE (REDUCING AGENT).
IF OXIDISED ARE ... THE REDUCING AGENT
IF REDUCE ... IS THE OXIDISNG AGENT.
AN OXIDISING AGENT IS ... A SPECIES (ATOM, MOLECULE OR ION) THAT OXIDISE ANOTHER SPECIES BY REMOVING ONE OR MORE ELECTRONS.
REDUCING AGENT ... REDUCES ANOTHER SPECIES GIVING IT ONE OR MORE ELECTRONS.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
