DISCUSS This boy swallowed a metal coin and then got ill Why did swallowing a coin make the boy ill? What is in the stomach which may have reacted with the coin? Reactions of acids with metals and metal carbonates LO: investigate and write equations for reactions of metals and metal carbonates with acid

What is your prediction? Reaction of Magnesium and hydrochloric acid

1. Wear goggles 2. Pour 1cm of HCl into a boiling tube, 3. Add a few pieces of Magnesium 4. Collect the gas in another boiling tube 5. Light a split and place it inside the test tube above the acid 1.How do you know a reaction is occurring? 2. How do you test for hydrogen gas? METHOD: Reacting metals with acids

Reactions of metal with acids equation metal acid salthydrogen zinc Eg.

More examples to fill in the gaps! Magnesium + hydrochloric acid  ______________ + ____________ ________ + hydrochloric acid  lithium chloride + hydrogen _______ + sulphuric acid  calcium sulphate + ___________ Nitric acid + potassium  ___________ + _____________ Aluminium + hydrochloric acid  __________ + _________ zinc chloride hydrogen lithium calcium

Practice- copy and complete 1.Nitric acid + potassium  2.Magnesium + hydrochloric acid  3.Zinc + sulphuric acid  4.Nitric acid + magnesium  5.Aluminium + hydrochloric acid 

Acids and metal carbonates Would you like to have a cup of tea from a kettle which looked like this? Limescale builds up in kettles, showers and water pipes

Limestone is Calcium Carbonate (CaCO 3 ) Discuss with your partner, How can we remove limescale from kettles and water pipes? What type of reaction is this? Make a prediction what will the products of the reaction be? Eg. I predict the products of the reaction will be

1. Wear goggles 2. Add 2 spatulas of CaCO 3 to the test tube, 3. Add 1cm of HCl 4. Connect the tubing to the limewater 1.How do you know a reaction is occuring? 2.What happens? What colour does the limewater go? What gas is being produced? METHOD: Reacting metal carbonates with acids

Reaction of metal carbonates with acid equation Metal carbonate acid Carbon dioxide gas watersalt Eg. Calcium Carbonate

Practice 1.Iron carbonate + sulphuric acid  2.Zinc carbonate + hydrochloric acid  3.Potassium carbonate + nitric acid 
