INVESTIGATING THE REACTION BETWEEN MAGNESIUM (Mg) AND HYDROCHLORIC ACID (HCL)

AIM!

The aim of the experiment is to find out the effect of concentration of acid, in the reaction between dilute Hydrochloric Acid and the Magnesium Ribbon. Depending on how fast the reaction takes place, indicates the rate of the chemical reaction, (how often the molecules collide). In the investigation I will test the different concentrations of acid reacting with the magnesium ribbon.

PREDICTION!

I predict that as the concentration of the hydrochloric acid decreases (becomes more diluted), the time taken for the magnesium ribbon to dissolve will increase. I also predict that as the concentration of the hydrochloric acid decreases, the rate of reaction will double.

BACKGROUND KNOWLEDGE!

The background knowledge is very important because it can give us an inkling as to what we think can happen in the experiment, and from using the background knowledge I can make a prediction, and then justify it. I know that there are certain aspects of the experiment that can change the course of the results. One of the factors is the 'Collision Theory'.

The Collision Theory describes how the
