Magnesium Oxide Reaction - Lab Report

Extracts from this document...


Aim: To observe the various mass changes of a magnesium ribbon before combustion and then again after combustion and then compare the results, using different lengths of magnesium ribbons. Hypothesis: My hypothesis is that the mass of magnesium after it reacts with oxygen will be greater than the original mass of magnesium before the reaction took place. Apparatus: * Crucible * Lid of the Crucible * A magnesium ribbon (2cm for our group) * Sand paper * Tongs * Bunsen burner * Tripod stand * Clay Triangle Method: 1. Take the magnesium ribbon and clean it with the sand paper 2. Measure the weight of the empty crucible with the lid on 3. ...read more.


Keep opening the lid after a few minutes for the oxygen to come in and react with the heating magnesium 11. After the magnesium ribbon is heated and when magnesium oxide is formed, measure the weight and compare the weight of magnesium with magnesium oxide. Safety Measures/Precautions: * Wear safety glasses while doing the experiment. * The magnesium ribbon burning should be done under a teacher as this may cause severe burns to the skin if touched. * Get the assist of a teacher or parent to do the experiment Diagrams: Pictures of burning of magnesium ribbon: Results: Mass of lid + crucible = 43.82g Mass of lid + crucible + magnesium ribbon = 43.85g Mass of magnesium ribbon = 3g After burning: Magnesium oxide + lid + crucible ...read more.


That was the only main error that may have altered our results slightly. Other than this our experiment, was without any errors. Conclusion: My hypothesis was proved correct at the end of the experiment, as the magnesium oxide mass was greater than the magnesium ribbon at the start of the experiment. The magnesium oxide seemed like white ash in color. Magnesium is one of the alkaline-earth metals, and is one of the most common elements in the Earth's crust. In its pure form, it is silvery white, and relatively soft, like ash. It burns in air with a brilliant white light, as seen in the experiment, and for this reason is often used in flares and fireworks. The equation is: 2Mg(s) + O2(g) --> 2MgO(s) -Rohan M ?? ?? ?? ??

  1. Iron Oxalate Lab

    An accurate result for the percent oxalate shows that the crystals in the first lab were synthesized correctly, and the titration process in the second lab occurred without error. The trials of titration used had an average of 30.2 ml their percent difference was low; enough to assume that there

  2. Rate of reaction of hydrochloric acid on magnesium.

    I noted the reading on the scale at the start. * I then measured 8cm length of Mg ribbon and inserted it into the conical flak and immediately placed the cotton wool on and started the stop clock. * I read the weighing scales every 15 seconds for 1minute and 30 seconds.

  1. Find out the theoretical yield of Magnesium Oxide, find the percentage yield of Magnesium ...

    48 grams of Magnesium makes 80 grams of Magnesium Oxide. To find one gram of Magnesium divide 48 with itself and therefore you have to do the same with 80 e.g. 48g of Mg ----------------------- > 80g of MgO 1g of Mg------------------------- > 1.6 I get 16 by dividing 80 with 48 which gave me 1.6.


    ( The scale is sensitive, so you might not get an exact value) 4. Pour 1 liter of water into a pan and boil it over a portable cooking heater until it begins coil. 5. Place the 50 grams of spaghetti into the pan and begin timing on the stop watch.

  1. Rate of reaction of different concentrations of sodium thiosulphate.

    This may have been caused by the concentration being to low as the water proportion is 4 times as greater than the sodium thiosulphate volume therefore the rate of reaction is very slow. In this case the water molecules are highly dominant than the Na2S2O3 molecules.

    * Next I took a 5cm magnesium strip, making sure the strip was flat, and dropped it in the all acid solution. * As soon I dropped the strip into the acid I started the timer. * I then stopped the timer when the magnesium had completely dissolved and recorded the time in my table.

    spilt, so on the main experiment the reaction will be carried out in a conical flask instead of a beaker and with cotton wool acting as a plug to stop acid splashing out, but at the same time allowing carbon dioxide to escape.
