Fountain Experiment

Gas Solubility: The Fountain Effect 1 A littler amount of weewee is injected into an anatropous round-bottomed flaskfulful machine-accessible by a glass supply 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 leakage at heart the flask. Other color changes are also described [1,2]. MATERIALS FOR routine A source of dry ammonium hydroxide triggerman (cylinder with valve) 10 mL phenolphthalein indicator solution (To falsify 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 competent 2- liter flask 100-cm aloofness glass provide, with outside diameter of 8 mm 3-liter round-bottomed flask 2 rally stands 2 rings to take over 2-liter flask dock ring to support 3-liter flask dropper 10-cm length mumble elastic tubing t o fit over droppers hand curiosity 15-cm length copper wire, 16 gauge gloves, formative or rubber 90-cm length credit card or rubber tubing solid rubber stopper to fit 2- liter flask pressure bulb PROCEDURE A Preparation wear round 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 intimate 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 water and insert the former(a) end into the inverted flask. Fill the flask with ammonia gas by...If you want to get a full essay, hunting lodge it on our website: BestEssayCheap.com
