COLLECTION METHOD OF OXYGEN
WHEN OXYGEN GAS COLLECT IN THE GAS JARS THE WATER IN IT MOVES DOWN AND GETS COLLECTED IN THE TROUGH. THIS METHOD IS NAMED AS COLLECTING GAS BY THE DOWNWARD DISPLACEMENT OF WATER. GASES THAT ARE INSOLUABLE or ONLY SLIGHTLY SOLUABLE IN WATER CAN BE COLLECTED BY THIS METHOD.
IDENTYFICATION OF OXYGEN
OBSERVE THE COLOUR AND ODOUR OF THE SAMPLE YOU COLLECTED. TURN THE GAS JAR UPWARDS AND INTRODUCE A GLOWING SPLINTER IN TO THE JAR AND IT WOULD REKINDLE. (LIGHT A TAPER OR EKEL AND BELOW OFF THE FLAME SO THAT ONLY THE GLOW REMAINS)IN THIS CASE THE GAS DOES NOT BURN, BUT THE GLOWING SPLINT ALONE REKINDLESTHIS SHOWS THAT OXYGEN IS NOT A COMBUSTIBLE GAS BUT ONLY A SUPPORTER OF COMBUSTION.
