# What affects the rate of reaction between Magnesium Metal and Hydrochloric acid?

Extracts from this document...

Introduction

What affects the rate of reaction between Magnesium Metal and Hydrochloric acid? Plan The Experiment We are going to measure the amount of gas given off when we combine Hydrochloric acid and Magnesium Metal. We will combine the reactants and collect the gas given off by using a gas syringe. Here is the word and symbol equation for what we are going to do. Hydrochloric acid + Magnesium Magnesium Chloride + Water HCl + Mg MgCl + H2O Method * First I will collect my equipment so I can take out the experiment, and set it up. * Then we will measure out 50ml of Hydrochloric acid and pour it into the side-arm flask. * Then we will measure out 6cm of Magnesium ribbon, because in our preliminary experiment we used 3cm and there wasn't enough to react, so we have developed from our preliminary experiment are now using 6cm of Magnesium ribbon. * Make sure all of the equipment is set up right and that the gas syringe is connected to the side-arm flask because we don't want any gas escaping as the results will not be accurate. ...read more.

This is the table of results I obtained from the second experiment on Crocodile Chemistry Concentration of Acid (M) Amount of Magnesium (g) Time taken to reach 100cm3 (secs) 1M 10g 3 0.80M 10g 7 0.60M 10g 19 0.40M 10g 72 0.20M 10g 480 In this table you can see that with the new strengths of acid have worked well and produced me with some good adequate results. Real Experiment This is the table of results that I obtained from the real experiment. Amount of Acid (ml) Amount of Water (ml) Amount of Magnesium (cm) Time taken to reach 100cm3 (secs) 50 0 3 ? 45 5 3 ? 40 10 3 ? 35 15 3 ? 30 20 3 ? We first tried this experiment with 3cm of Magnesium (above) and we found that it wasn't enough to react with the acid and produce enough Hydrogen. So we then tried it with 6cm of Magnesium, and could then obtain some results, as there was enough Magnesium to react with the Hydrochloric acid. We then drew up another table to show our new readings. ...read more.

Conclusion

In my experiment I did not get any anomalous results as you can see on my graph. This shows us that the experiment went well and was fair. It was fair because no gas escaped from one experiment and not from another. If I were to endeavour the experiment again I would. * Try to be a bit quicker getting the bung onto the side-arm flask as a little bit of gas was escaping from the top of the flask. * Clean the gas syringe before and after every time it is used, so it will be clean and be able to slide in and out easily to make the test even fairer. * Remember to start the stop clock at the exact time of the Hydrochloric acid and Magnesium combining and reacting. To improve the reliability of my results I would attempt the whole experiment again a few times to see if I could get the same results, and make them become more reliable. Also I would try to find a textbook with this experiment and some results in it, either at school, in the library or on the Internet. I would then copy and paste the results in a table on to my work to make my results more reliable. Andrew Marshall 10 A 3 ...read more.

I predicted that the curves would bend from a steep line to a horizontal line and the faster the reaction the steeper the curve would start and the quicker it would reach a horizontal line. This is because as the reaction starts it is very quick and as the chemicals

In out main experiment we are going to choose a 15mm piece of magnesium with acid. The experiment will be repeated three times to make sure our results are accurate. We have also done 20mm and 10mm of magnesium in 10ml of acid with 20ml of water.

* Place the conical flask containing the Sulphuric acid, in the beaker of either ice to cool or heated water to heat and wait for it to reach target temperature check with a thermometer. * Take the conical flask out of the beaker once it is at the correct temperature and place 1 magnesium ribbon (8cm)

2. ## Investigate 'How much gas is released when a metal reacts with an acid.'

It is a rule. Knowing this makes it easy to work out how much Hydrogen will be produced when different amounts of Magnesium is used because as: 24g of Magnesium will make 24L of Hydrogen (24000cm�), 0.24g of Magnesium will make 0.24L of Hydrogen (240cm�), and 0.024g will make 0.024L of Hydrogen (24cm�)
