properties of some common gases

GASES	NATURE	DENSITY[V.D o of air =14.4]	SOLUBILITY[in water]
NITROGEN	Neutral Colourless Odourless Tasteless Non-toxic	V.D = 14 – almost equal to air	100 volumes of water dissolves about 2.3 volumes at 30^oC. Slightly soluble.
OXYGEN	Neutral Colourless Odourless Tasteless Non-toxic	V.D = 16 - 1.1 times heavier than air	100 volumes of water dissolves about 4 volumes at S.T.P --- Slightly soluble
CHLORINE	Acidic Greenish yellow Choking odour Sour taste Poisonous/Toxic	V.D=35.5 2.5 times heavier than air.	1 volume of wate dissolves avout 2.7 volumes at 15^oC. Fairly soluble
CARBON MONOXIDE	Neutral Colourless Odourless Tasteless Poisonous	V.D = 14 Almost equal to air.	100 volumes of water dissolves about 3.5 volumes at 0^oC -slightly soluble
CARBON DIOXIDE	Slightly acidic Colourless Odourless Slight sour taste Non-poiisonous	V.D = 22 1.5 Times heavier thain air.	1 volume of water dissolves abour 1 volume of gas. -Fairly soluble.
