Aim Determining the identity of an unknown metal. Measurement of gas volume, calculations with gases based on reaction equations. Substances 10% solution of hydrochloric acid, 5,0...10,0 mg piece of a metal. Equipment Apparatus for measuring the volume of gas, measuring cylinder (25 cm 3), funnel, filter paper, thermometer, barometer and hygrometer. Experimental procedure 1. The experimental apparatus (Figure 1) consists of two burettes connected with a rubber hose (a), which is filled with water. One burette is connected to a test tube (b), in which the metal reacts with the acid. 2. Preparation for the experiment. Remove the test tube and wash it carefully with distilled water. Firmly attach the test tube back. Adjust the burettes to the same height and check
