Determination of the molar volume of hydrogen gas

Extracts from this document...

Introduction

Determination of the molar volume of hydrogen gas Introduction We are going to determine the molar volume of hydrogen gas by letting known amount of magnesium react with dilute hydrochloric acid and carefully collecting the gas formed. Materials Gas syringe Hydrochloric acid, 2-molar 8 cm of magnesium ribbon Ruler Emery cloth For details see instruction form Methods We connect the equipment according to the diagram and make sure we follow the instructions carefully, and then we weigh the 8 cm of magnesium ribbon and pour the HCl into the test tube. ...read more.

For details see instruction form. Results: Measured weigh of 8 cm mg ribbon: 0.068 g (uncertainty is � 0.0001) Room temperature: 21.9 �C (uncertainty is � 0.1) Room pressure: 742.5 mmHg Vapour pressure of water: 19.587 and 19.827 Vapour pressure: 19.587 + 19.827 / 2 = 19.707 1.333 x 102 x (mmHg) = Pa Convert the room pressure in mmHg into Pa: 742.5 x 1.333 x 102 = 98975.25 Pa Convert the vapour pressure of water into Pa: 19707 x 1.333 x 102 = 2626.9431 p(H2O) ...read more.

Conclusion

V2 = 59cm3 (uncertainty is �0.5) T1 = 21.9 �C = 294.9 K (uncertainty is �1.3466 ) T2 = 0 �C = 273 K 96348.3069 x 70 x 1 / 294.9 = 101300 x 59 x 0.5 / 273 Conclusion & Evaluation: Our conclusion is that the molar volume of hydrogen gas at 0 �C and 1 atmosphere is -. We reached the conclusion by first checking the room temperature and barometer pressure. Then we looked up the values for vapour pressure of water at the actual temperature from the Hand book of Chemistry and Physics. The full reference is: Chemistry for the IB diploloma G. Neuss.

    While the magnesium was in the HCl it bubbled, which floated vertically to the top of the gas collecting tube. When the magnesium was first added it reacted rapidly producing bubbles at a quick rate, but as the experiment went on, the speed and bubbles became more gradual and slower

    Also, to make sure the needle of the gauge did not stick, the gauge was gently tapped before a pressure reading was taken. Design for the collection of sufficient relevant data: 1. To begin with, the 20.0 cm3 syringe was filled with 20.0 cm3 of nitrogen gas, the stopcock closed,

    2. Describe the relationship between the two variables and indicate any proportionalities that exist. From the graph we can see that as the moles of hydrogen increase, the volume of hydrogen is also increased. Analysis Section 3. From the graph determine the volume of hydrogen when the number of moles of

    As seen in Graph 2.1 there is a negative correlation between the volume and the pressure of the confined gas ? indirectly proportional. For example, when the confined gas is at a volume of 0.055 dm3 the pressure exerted is equal to 99.9 KPa, however when the confined gas is

    This resulted in the volume being larger than expected. I could have taken more precautions and done it slowly to make sure there are no air bubbles inside the tube. Some of the hydrogen started reacting with the magnesium ribbon as soon as the magnesium ribbon was put into the water.
