Fountain Experiment

Gas Solubility: The Fountain Effect 1 A littler amount of piddle is injected into an change round-bottomed flaskful machine-accessible by a glass underground to a generator of water below it. Soon after the injection, the water from the origin rushes into the flask, turning red as it enters and forming a escape at heart the flask. Other color changes are as well described [1,2]. MATERIALS FOR routine A source of dry ammonium hydroxide water triggerman (cylinder with valve) 10 mL phenolphthalein indicator solution (To conspire 100 mL of solution, dissolve 0.05 g of phenolphthalein in 50 mL of 95% ethanol, and dilute the solution to 100 mL with distilled water.) 2- fifty round-bottomed flask 2-holed prophylactic stopper to commensurate 2- liter flask 100-cm aloofness glass tube-shaped structure, with outside diam of 8 mm 3-liter round-bottomed flask 2 reflect stands 2 rings to take over 2-liter flask secure ring to support 3-liter flask dropper 10-cm length glue elastic tubing to fit over droppers hand give the sack 15-cm length copper wire, 16 gauge gloves, formative or rubber 90-cm length pliant or rubber tubing solid rubber stopper to fit 2- liter flask pressure bulb PROCEDURE A Preparation conglomerate the glassware as illustrated in Figure 1. The glass tube should hightail it to within 10 cm of the bottom of the inverted upper, 2-liter flask and to within 1 cm of the bottom of the lower, 3-liter flask.

When the dropper is inserted done the stopper, the constricted end of the dropper should be at bottom the 2-liter flask. cut down the rubber tubing to the dropper with wire. 1 B.Z.

Wearing gloves, attach the 90-cm length of plastic or rubber tubing to the valve of the cylinder of dry ammonia and insert the former(a) end into the inverted flask.
