Reaction of Acid and Reactive Metal (+ test for hydrogen gas)

In this experiment, we will look at the reaction of hydrochloric acid and magnesium metal to form magnesium chloride salt and hydrogen gas.

Test for hydrogen gas: Place a lighted wooden splint at the mouth of the test tube

Observation: If hydrogen gas is present, the lighted splint extinguishes with a 'pop' sound.

Content suited for Lower Sec Science (Chemical Changes), and Upper Sec Chemistry (Acids and Bases / Salts).

Well done Raquel 👍🏻👍🏻 .. Putting a stopper over the test tube with Mg + HCl is important to collect enough H2 gas for a good & effective pop sound 💥
