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
Aim: To investigate the effect of concentration on the rate of the reaction between magnesium ribbon and hydrochloric acid.

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:

  1. Tie back hair, tuck in ties, put on safety goggles and assemble equipment (see diagram).
  2. Measure 6cm3 of hydrochloric acid and 14cm3 of water with a measuring cylinder. Pour this (0.6 moldm-3) into the conical flask.
  3. Measure and cut 3cm of magnesium ribbon.
  4. 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.
  5. Every ten seconds record the amount of hydrogen produced. Read off the measuring cylinder and...
