The Effect of Temperature on The Rate Of Reaction Between Magnesium And Hydrochloric Acid
Planning
I'm planning on investigating how temperature effects the reaction
between magnesium and hydrochloric acid, the experiment will show
whether the reaction will speed up or slow down with the change in
temperature. Temperatures will range from room temp up until 70
degrees.
The investigation will be a fair test because all quantities will
remain the same for each test, each test will use the same amounts of
hydrochloric acid and same size of magnesium, also the concentration
of the acid will also not be changed.

· Stopwatch

· Measuring jug
· Goggles
Whilst doing the experiment there are many things that will have to
remain the same in order to keep the tests fair, these include amounts
and measurements as well as concentration and size and shape of the
magnesium e.g. long strands. The temperature how ever will be the main
change in the experiment, this is the only factor to change in less
problems occur where a change is not optional. For each temperature
the test will be taken three times to make sure that the results are
correct and as accurate as possible, an average will be taken to give
a clear and single result.

Safety- To ensure that the investigation is safe I will make sure that
all equipment it correctly assembled, and I am wearing the appropriate
safety wear and that everybody around is either dressed correctly or
far enough away. Also the investigation will be performed in a
sensible manner and there is no dangerous behaviour.
Prediction
When the experiment is taking place I believe that the magnesium in
the hydrochloric acid will begin to bubble and then disappear, I also
the acid was at 14 C the magnesium took 141 seconds to react and 27 C

The first step that we took to accomplish our goal was to put on our safety goggles and choose a lab station to work at. We received one 400ml beaker, one polyethylene pipet, two test tubes with hole rubber stoppers, two small pieces of magnesium (Mg), one thermometer and a vial of hydrochloric acid (HCl). We took the 400ml beaker and filled it about 2/3 full of water (H20) that was 18 OC. Then we measured our pieces of Mg at 1.5 cm and determined that their mass was 1.36*10-2 g. We filled the pipet 2/3 full of HCl and poured it into one of the test tubes. Then, we covered the HCl with just enough H2O so that no H2O would be displaced when the stopper was inserted. After inserting the stopper, we placed the Mg strip into the hole, inverted the test tube and placed it in the 400ml beaker. HCl is heavier than H2O, so it floated from the tube, into the bottom of the beaker, reacting with the Mg along the way to produce hydrogen gas (H2). We then measured the volume of the H2, cleaned up our equipment and performed the experiment a second time.
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.
This would influence the results by making the reaction perform better. Without contaminates the two compounds can react with just each other instead of what has contaminated the water. The second assumption is that the water is just a vessel for the chemical reaction between magnesium hydroxide and citric acid. Assuming that magnesium hydroxide and citric acid don’t individually react with water this would make the water a vessel. Due to part one and part three of the lab this assumption is incorrect.
* It was almost impossible to tell when the Alka-Seltzer tablet had dissolved, each time the experiment was done. This was a huge problem for the experiment as this could have totally caused problems to the experiment. A special type of detector apparatus, which bleeped when the correct amount of Alka-Seltzer tablet dissolved, could improve this, each time the experiment was done.
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
The aim of my investigation is to find out whether the increase of temperature increases the rate of reaction between the two reactants of Sodium Thiosulphate and Hydrochloric acid. I will then find out and evaluate on how temperature affects this particular reaction. Factors There are four main factors, which affect the rate of reaction that are considered as variables for the experiment I will be doing, they are the following: Molecules can only collide when two of them meet together.

The Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Planning. CaCO3 (s) + 2HCl (aq) ---- CaCl2 (aq) + H2O (l) + CO2 The rate of reaction depends on how hard and how often the reacting particles collide with each other. A rate of reaction is how fast a reaction takes place.
Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.
If there is not enough energy no reaction takes place. In a solution of 0.5M hydrochloric acid, there are less hydrochloric acid particles compared to that of 2M hydrochloric acid, therefore, there are less particles to react with magnesium particles thus meaning less chance of collisions between the two reactants: [IMAGE] Therefore, as the concentration of the hydrochloric acid is increased, the chances of collisions increase thus giving a faster rate of reaction. Apparatus: Beaker Hydrochloric acid Distilled water Measuring cylinder Pipette Test tubes Test tube rack Diagram: [IMAGE] Method: Measure out 10cm3 of hydrochloric acid, as the concentration requires, for each concentration its composition is: Moles Volume HCl Volume Water 2M 10 cm³ 0 cm³ 1.5M 7.5 cm³ 2.5 cm³ 1M 5 cm³ 5 cm³ 0.5M 2.5 cm³ 7.5 cm³ 0M 0 cm³
Conclusion This experiment was set out to find the effect of different temperatures of hydrochloric acid on the rate of reaction with magnesium. The information recorded was then interpreted and compared to the hypothesis. From this information, a conclusion can be made to show that the rate of reaction relates to temperature in the reaction between hydrochloric acid and magnesium. In conclusion, as proven in this experiment, the higher the temperature of hydrochloric acid, the faster the reaction it has with magnesium.
