Unformatted text preview: tube. The tube was inverted and quickly placed into a beaker of distilled water. The HCl proceeded to settle to the bottom of the beaker and reacted with the metal within the copper wire forming bubbles of hydrogen gas which rose to the top of the tube. Once the metal was completely reacted the volume of gas was measured and recorded. Temperature was also found by inserting a thermometer into the beaker and recorded. The distance from the top of the tube to the surface of the water in the beaker was measured and this number was converted from cmH 2 O to mmHg so it could be used in calculating the pressure of hydrogen within the tube. The equation for calculating pressure of hydrogen gas (P H 2 ) is as follows:...
