We are trying to find out if temperature affects the rate of reaction between Hydrochloric acid and Magnesium.
I think that the higher the temperature of the acid rises, the rate of reaction will increase.
For example: If I double or triple the reaction, the rate of reaction will also double or triple.
As the liquid particles bash into the solid they may knock of a solid particle. This collision would therefore cause a reaction. Liquid particles need to hit the solid particles if they are to have any chance of breaking the bonds between the solid particles.
Keep the volume of acid the same throughout the entire experiment (20 cm²)
Keep the length of the magnesium the same throughout the entire experiment. (3cm)
Always use the same concentration of acid (1 Molar)
Hydrochloric acid (1 Molar)
Magnesium ribbon
Scissors
Flask
Measuring cylinder
Bunsen Burner
Tripod, Gauze + Heatproof Mat
Thermometer
Stopwatch
Splint
Goggles
Wire Gauze
1. You set up the experiment as shown above.
2. Measure the correct amount of acid (20cm²)
3. Put it in the flask.
4. Heat the acid (without the magnesium) to the right temperature.
5. Once you have reached the right temperature(s) take the flask of the wire gauze and put the magnesium into the acid.
6. Time how long it takes for the magnesium to completely finish reacting with the acid and put it into your results.
Wear goggles.
Don't touch anything that has just been heated.
Stand up and put stuff like books and pencil cases away.
Wash your hands thoroughly with soap and water if you have spilt acid on...
