Oxygen in air, by (1) absorption with phosphorus; (2) absorption with potassium (or sodium) pyrogallate; (3) by explosion with hydrogen. APPARATUS. 39 I. DETERMINATION OF OXYGEN IN AIR. (i) By Phosphorus.—100 cc. of air are measuredout as with the Orsat apparatus, the burette beingallowed to drain two minutes. The rubber connectorsupon the burette and pipette are filled with water, thecapillary tube inserted, as far as it will go, by a twist-ing motion, into the connector upon the burette, thusfilling the capillary with water; the free end of thecapillary is inserted into the pipette connector, thelatter pinched so as to form a channel for the watercontained in it to escape, and the capillary twisted andforced down to the pinch-cock. There should be aslittle free space as possible between the capillaries an
