My aim in this experiment is to react hydrochloric acid with magnesium in different concentrations to see if gas will be produced quicker or to see a change in rates of reaction.

Planning

My aim in this experiment is to react hydrochloric acid with magnesium in different concentrations to see if gas will be produced quicker or to see a change in rates of reaction.

I am going to wear goggles as a safety precaution as the acid may end up in an eye. As another precaution I am going to be careful when handling the acid and magnesium and I will not eat the magnesium or drink the hydrochloric acid.

Method

I am going to make sure that this will be a fair test. To do this I am going to use the correct amount of acid in each experiment and I will use the same amount of magnesium in each experiment as well.

We are going to change the concentration of the acid by adding 5cm cubed of acid in the first and 0cm cubed of water , in the second I will change the concentration and use 4cm cubed of acid and 1cm cubed of water, in the third I will use 3cm cubed of acid and 2cm cubed of water, in the fourth I will use 2cm cubed of acid and 3cm cubed of water and in the fifth and final one I will use 1cm cubed of acid and 4cm cubed of water.

To do this experiment I am going to use:

Gas syringe,

Clamp,

Clamp stand,

Boss,

Ruler,

Scissors,

Measuring Cylinder,

Stop watch,

Test tube rack,

6 Test tubes,

Hydrochloric Acid,

and Magnesium.


Prediction

I predict that if I increase the concentration of the hydrochloric acid the quicker the rate of reaction will be. This is because there are more particles to react with in the stronger concentration.
