CHAP 7 /3

QuestionAnswer
IODINE REACT WITH THE RED ALLOTROPE OF PHOSPHORUS TO FORM ... PHOSPHORUS TRIIODIDE. 2P + 3I2 à 2PI3.
IF MIXTURE OF PI3 IS DAMP THEN ... CAN REACT WITH WATER TO FORM HYDROGEN IODIDE GAS. PI3 + 3H20 à 3HI+H3PO3
(THIS HOW GASEOUS HYDROGEN IODIDE IS PREPARED.)
HOW IS GASEOUS HYDROGEN IODIDE PREPARED .. MIXTURE OF PI3 IS DAMP THEN ...CAN REACT WITH WATER TO FORM HYDROGEN IODIDE GAS. PI3 + 3H20 à 3HI+H3PO3
A HALOGEN WILL DISPLACE A LESS REACTIVE HALOGEN.
WHEN CL- BUBBLED IN KBR ... CL- OXIDISES THE BROMIDE IONS. BROWN BROMINE IS FORMED. CL2 + 2BR-àBR2 + 2CL- . THE CL- MOLECULE GAIN 2 ELECTRONS FORM EACH BROMIDE ION : 2BR-(AQ) à BR2(AQ) + 2E-. CL2(G) + 2E- à 2CL-(AQ).
CL DISPLACES ... IODINE FROM IODIDES
WHEN CHLORINE DISPLACE IDODINE WHAT DOES IT FORM .. A DARK GREY PRECIPITATE OF IODINE CL2 + 2I- à I2 + 2CL-.
BROMINE ALSO DISPLACES ... IODINE FROM IODIDES BR2(AQ) + 2I-(AQ) à I2(S) +2BR-(AQ).
THE DISPLACEMENT OF BR BY CL- IS USED IN ... EXTRACTION OF BROMINE SEAWATER , HAS SMALL AMOUNT OF BR IONS.
IODINE IS THE LEAST REACTIVE SOO... WILL ALWAYS BE DISPLACED
CL GAS IS BUBBLED INTO SEAWATER & BR PRODUCED IS ... REMOVED BY BLOWING AIR THROUGH THE SOLUTION.
(SEAWATER )ON COOLING THE BROMINE VAPOUR ... CONDENSES IS COLLECTED.
IODINE IS ONLY VIOLET WHEN .. A GAS OR DISSOLVED IN HEXANE OR TETRACHLORIDE.
HOW DOES CL REACT WITH WATER ... REVERSIBLE TO FORM HCL ACIDIC AND WEAK ACID CHLORIC (I) ACID.
WHAT DOES CL FORM WHEN REACTED IWTH WTAER ... HCL ACIDIC AND WEAK ACID CHLORIC (I) ACID THE SOLUTION ACIDIC COZ THE H+.
H+ IONS MAKE SOLUTIONS ... ACIDIC
REACTION OF CL WITH WATER IS WHAT TYPE OF REACTION... WHY? THIS IS A DISPROPORTIONATION REACTION. CL2- STARTS IN 0 OXIDATION STATE & IS REDUCED TO -1 IN CL- ION AND OXIDISED TO +1 IN CHLORIC (I) ACID HOCL. CL- IS SIMULTANEOUSLY OXIDISED AND REDUCED.
HOW DOES FLUORINE REACT WITH WTAER... IRREVERSIBLY WITH WATER FORM HYDROGEN FLUORIDE AND OXYGEN.
WHAT IS FORMED WHEN F-(G) + H20(L) ... HF AND O2.
HOW DOES BROMINE REACTS WITH WATER (REVERSIBLEY WITH WATER ) BUT POSITION OF EQUILIBRIUM MORE ON LEFT.
BR2(AQ) + H2O(L) REVERSIBLE ARROWS H+(AQ) + BR-(AQ) +HOBR (AQ)
HOW DOES IODINE REACT WITH WATER ... IODINE DOESN’T REACT WITH WATER.
ALKALI AT ROOM TEMP CL- BR-I-ALL REACT WITH COLD AQUEOUS NAOH ... BY DISPROPORTIONATION REACTIONS FORM MIXTURE OF HALIDE AND HALATE (I) SALTS
DISPROPORTION REACTION WITH CL AND COLD AQUEOUS NAOH ... CL2(0) + 2NAOH àNACL(-1) + NAOCL(+1) +H2O. THE CL IN ZERO STATE REDUCED TO -1 IN NACL AND OXIDISED TO +1 IN NAOCL (SODIUM CHLORATE (I)). IONIC EQUATION IS: CL2(AQ) + 2OH- (AQ) à CL-(AQ) +OCL (AQ) +H20(L).
F- REACTS IRREVERSIBLE WITH WATER TO FORM HYDROGEN FLUORIDE AND OXYGEN. CL IS TOTALLY IONISED INTO H+ AND CL- IONS.
WHEN BOLIING ARE HF BOND BROKEN ...WHY ? NO HF HAS INTERMOLECULAR BONDS, COVALENT BONDS

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.
