Chemistry Rate of Reaction
Summary: An overview of an experiment to test the effects of concentration on the rate of reaction between a magnesium ribbon and hydrochloric acid. Includes an outline of the experiment and an analysis of its results.
Chemistry
Factors that affect the rate of reaction:
- Temperature
- Surface area
- Concentration
Reaction:
Magnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen
Mg + 2HCl MgCl2 + H2
Apparatus: Measuring cylinder, delivery tube, bung, conical flask, magnesium ribbon, water, 2moldm-3 hydrochloric acid, trough, beehive shelf.
Diagram of apparatus:
Method:
- Tie back hair, tuck in ties, put on safety goggles and assemble equipment (see diagram).
- Measure 6cm3 of hydrochloric acid and 14cm3 of water with a measuring cylinder. Pour this (0.6 moldm-3) into the conical flask.
- Measure and cut 3cm of magnesium ribbon.
- Add the magnesium strip to the acid in the conical flask and quickly put the bung in the flask, so no hydrogen will escape. Start the stopwatch immediately.
- Every ten seconds record the amount of hydrogen produced. Read off the measuring cylinder and...
