The Theoretical and the Actual Volume of Hydrogen Gas
The Theoretical and the Actual Volume of Hydrogen Gas
The hypothesis was proven right. From the result of this experiment, it could be seen that there are only a few differences between the theoretical and the actual volume of hydrogen gas. This means that by creating a reaction of magnesium and hydrochloric acid, the volume of hydrogen gas at STP can be calculated. Although trial 1 and 2 had resulted differently from each others, the percent error was similar (9.9% and 9.5% respectively). The molar volumes calculated were 24.61L/mol and 34.53L/mol. This experiment was pretty simple. A small amount of magnesium ribbon(approximately 4.5) was inserted into a piece of copper wire (approximately 20cm). Then, in order to create a 2M HCl solution with a 6M Hcl solution, we had to calculate the amount of HCl and water we needed. [MV = MV] Since there was a 6M solution, and a 15mL 2M solution of HCl was required, [ (6)(x)=(2)(15) ] x=5, 5mL of 6M HCl was added to 10mL of water. This made a 2M HCl solution because 1/3 of the solution is 6M HCl, which means, overall its 2M HCl solution. The obtained acid was then poured into the eudiometer. After pouring in all the acid, distilled water was poured into the eudiometer until it was full of the solution. The eudiometer was slightly tipped just in case of the mixture of water and acid. The stopper with the hooked copper was then inserted into the end of the eudiometer. Then, it was put into a 400mL beaker filled with water. The acid reated with the magnesium; after the reaction was complete, the eudiometer was put into a graduated cylinder filled with water. The water level in the tube had to be in the same level of th water in the graduated cylinder. The volume of hydrogen gas was recorded. Then, the room temperature was measured by placing a thermometer into the room-temperature
