Magnesium Ribbon Essay

Decent Essays
Title-

Aim- The aim is to investigate the effect of concentration on the temperature result from the magnesium ribbon reaction in hydrochloric acid.

Background Information- The rate of reaction is a term that relates to the speed at which the reaction occurs. This is the speed that the magnesium ribbon will take to dissolve in each test tube. The time that the magnesium ribbon takes to dissolve will probably be different as there are different amounts of hydrochloric acid in each tube. Exothermic is the term that refers to the temperature that develops from the magnesium ribbon dissolving in the hydrochloric acid. The temperature varies depending on the rate of reaction and the concentration of hydrochloric acid in the test tube. The

Risk Assessment-
Wear safety goggles to reduce the possibility of HCL

Method-
1. Pour 10ml of hydrochloric acid into a 25ml test tube this is a 100% solution.
2. Pour 5ml of hydrochloric acid into a different test tube. Pour in 5ml of distilled water this is a 50% solution.
3. Pour 2.5ml of hydrochloric acid into the third test tube. Pour in 7.5ml of distilled water which is a 25% solution.
4. Measure the temperature of each solution to ensure they are the same temperature using a thermometer.
5. Drop a piece of 2.5cm long magnesium ribbon into the 100% solution and start timing the reaction, stir gently at first using the glass stirring rod to make sure the magnesium doesn’t stick to the side of the test tube.
6. Record the time and measure the temperature of the solution after 1 minute since the magnesium being placed inside the solution.
7. Repeat the procedure with the other solutions 25% solution and 50% solution recording the temperature at 1 minute.
8. Record results using appropriate table
9. Draw an appropriate graph using results.
