Reactions of metals with acids • How much can you remember? • Have a conversation with your partner to revise what you know! (2 min) • Now, can you remember more? • Let’s carry out the experiment in your booklet! (15 min)

Reaction of metals with acids When a metal reacts with an acid, the products

Reaction of metals with acids When a metal reacts with an acid, the products are a salt and hydrogen gas. metal + acid salt + hydrogen The salt produced depends on the metal and type of acid involved in the reaction: l When a metal reacts with hydrochloric acid, the salt produced is a metal chloride. l When a metal reacts with sulfuric acid, the salt produced is a metal sulfate. The hydrogen ions of the acid form hydrogen molecules (H 2) during the reaction and these are given of as a gas.

Metal reactions with acids Many metals react with acids. When this happens, effervescence or bubbling occurs. What do the bubbles indicate? A gas is produced. Where might this gas have come from? How can you test to find out if the gas produced is hydrogen? Place a burning splint next to the mouth of the test tube. A ‘squeaky pop’ as the gas ignites shows that hydrogen is the gas produced in this reaction.
