Reaction of metals with acids Year 8

Learning objectives Compare the reaction of metals with acids Write word equations for the reaction of metals with acids. Write balanced symbol equations for the reactions.

Reaction of metals with acids Calcium + hydrochloric acid → Calcium chloride + water Why does copper react the least? Zinc + sulphuric acid → Mg + 2HNO3 →

Reaction of metal carbonates with acids When a metal carbonate reacts with an acid, it fizzes giving off carbon dioxide gas. Carbon dioxide can be tested for using the limewater test. When carbon dioxide gas is bubbled through limewater, it turns the limewater cloudy or milky white. Most metal carbonates are not very soluble and so the reactions may be slow.

Reaction of metal carbonates with acids When a metal carbonate reacts with an acid, the products are a salt, carbon dioxide and water. metal carbonate sulfuric acid nitric acid acid hydrochloricacid metal nitrate salt metal sulfate metal chloride carbon dioxide water The salt produced depends on the metal carbonate and type of acid involved in the reaction: When a metal carbonate reacts with hydrochloric acid, the salt produced is a metal chloride. When a metal carbonate reacts with sulfuric acid, the salt produced is a metal sulfate. When a metal carbonate reacts with nitric acid, the salt produced is a metal nitrate.

Complete the word equations metal carbonate acid salt carbon dioxide water Complete the word equations Complete the word equation for each reaction between a metal carbonates and an acid: sodium carbonate ? nitric acid sodium nitrate ? carbon dioxide water ? calcium carbonate nitric acid calcium nitrate carbon dioxide water zinc carbonate sulfuric acid ? zinc sulfate carbon dioxide ? ? water
