The tube through the bung should be a short section of glass, and then a flexible rubber tube can be connected. Ensure that all naked flames are extinguished, and that there are no other sources of ignition available to students. It is best if the students work in pairs because setting up and starting the experiment requires more than one pair of hands.

Some students might notice the flask becoming slightly warm and they could be asked how this would affect the rate of reaction, and how they might adapt the experiment to make it a fair test. The reaction is exothermic, but the dilute acid is in excess and the rise in temperature is only of the order of 3. Students should not have access to any source of ignition.

An inhibitor decreases the number of collisions between the particles, effectively by reducing either the concentration or the surface area of reactants or catalyst. This practical chemistry resource was developed by the nuffield foundation and the royal society of chemistry. If a graph of volume (y-axis) against time (x-axis) is drawn, the slope of the graph is steepest at the beginning. When you are ready, add a 3 cm strip of magnesium ribbon to the flask, put the bung back into the flask as quickly as you can, and start the stopwatch.

    During any chemical reaction the concentrations of reactants decrease and the concentrations of products increase. Fill the other measuring cylinder with water, and make sure that it stays filled with water when you turn it upside down. An inhibitor decreases the number of collisions between the particles, effectively by reducing either the concentration or the surface area of reactants or catalyst.

    The magnesium ribbon should be clean and free from obvious corrosion or oxidation. Students follow the rate of reaction between magnesium and the acid, by measuring the amount of gas produced at 10 second intervals. Syringes should not be allowed to become wet, or the plungers will stick inside the barrels.

    During the experiment, one student can take the readings while the other records them. But these are very expensive and are probably best used by the teacher in a demonstration. However the acid is in excess, so it is mainly the loss of magnesium (surface area becomes smaller) that causes the change in the rate. An increase in temperature results in an increase in the kinetic energy of the particles, so more will have the required activation energy for successful collisions.
