Title: An investigation into finding the reactivity of different metals using different tests.

Aim: To design a series of tests that will allow 5 unknown metals to be placed in there order of reactivity.

Hypothesis: It is predicted that a metal giving more gas out of a test tube during the test will be more likely to have a higher reactivity. It predicted that a metal giving less gas out of a test tube during the test will be more likely to have a lower reactivity.

Diagram:

Apparatus: Test tube, delivery tube, water bucket, bung, beaker, pipette, tripod, Bunsen burner, chronometer, electronic balance.

Plan: Measure 0.30 grams of 5 different metals Place retort stand over Bunsen burner. Pour 5 ml of water using a pipette into a test tube. Attach test tube to the retort stand and boil the water. Place the metal into the test tube and at the same time start a chronometer. Stop the chronometer when metal has reacted. Do the same for the 4 different metals. Pour 5 ml of hydrochloric acid into a test tube. Measure 0.30 grams of 5 different metals. Fill a trough of water and submerge a measuring cylinder into the water. Place a delivery tube, so that it connects to the measuring cylinder. Place the metal in the test tube. Quickly connect the delivery tube to the test tube. Start a stopwatch. Measure the gas volume after 2 minutes. Do the same for all four other metals.
