The Rate Of Reaction Between Magnesium And Hydrochloric Acid

Aim

My aim is to see how the rate of reaction between magnesium and

hydrochloric acid is affected by changing the length of magnesium.

Hypothesis

I predict that if the length of magnesium is high then rate of

reaction will be much more longer because if the length of magnesium

is more then it will take longer to dissolve and therefore it will

react for a longer time.

Apparatus

=========

o Measuring cylinders

o Boiling tube

o Ruler

o Stop Watch

o Magnesium ribbon

o 2 molar hydrochloric acid

o Water

Plan

====

First I will set up the experiment then I will put 15cm cubed of

hydrochloric acid and 15cm cubed of water inside the boiling tube. I

will then put in a 0.5cm long piece of magnesium into the tube and I

will start the stopwatch and I will see how long the magnesium reacts

for before dissolving in the solution.

The experiment will be repeated again on numerous occasions but the

length of magnesium will be changed. I will do this by adding 0.5cm to

the length of magnesium each time.

I will repeat the experiment in order to get some accurate results.

After repeating the experiments I will have two sets of results, I

will work out the average and then I will plot the graphs.

The way that my experiment will be made fair is that only one thing

will be changed and that is the length of magnesium but all the other

things that can have an effect on the outcome will be kept the same

e.g. temperature and volume of liquid. This experiment will be done at

room temperature therefore the temperature is the same all through the

experiment. The same concentration will be used through the

experiment. (The first experiment that I will do will look at the

effect different concentration has on the
