  2. answer 1 Give an everyday example of neutralisation. Reducing acidity in soil by adding lime, treatment of acid indigestion Calderglen High School

  3. answer What is Neutralisation? 2 The reaction of an acid with a base to form water Calderglen High School

  4. answer 3 What happens to the pH of an acid as it is neutralised? The pH INCREASES to 7 Calderglen High School

  5. answer 4 Give some examples of bases (things that can neutralise acids) • alkali (metal hydroxide), • metal oxide, • metal carbonate Calderglen High School

  6. answer 5 Name the products of the reaction between a dilute acid and an alkali Salt and water Calderglen High School

  7. answer 6 Complete the word equation Acid + Alkali  Salt + Water Calderglen High School

  8. answer 7 Name the products in the reaction between a dilute acid and a metal carbonate. Salt, water and carbon dioxide Calderglen High School

  9. answer 8 Complete the word equation Salt + Water + Carbon dioxide Acid + Metal  carbonate Calderglen High School

  10. answer Name the salt produced in the reaction: hydrochloric acid + copper carbonate 9 Copper chloride Calderglen High School

  11. answer 10 Name the products of the reaction between a dilute acid and a metal oxide Salt and water Calderglen High School

  12. answer 11 Complete the word equation Acid + Metal  oxide Salt + Water Calderglen High School

  13. answer Complete the word equation? 12 Potassium nitrate Nitric + Potassium  + Water acid hydroxide Calderglen High School

  14. 13 answer Name the products of the reaction between potassium hydroxide and dilute nitric acid potassium nitrate and water Calderglen High School

  15. answer What is a base? 14 A substance which neutralises an acid Calderglen High School

  16. answer 15 Identify the two bases.sodium chloride, sodium oxide, calcium nitrate, copper carbonate sodium oxide and copper carbonate Calderglen High School

  17. answer 16 What type of chemical reaction is taking place when copper oxide is added to dilute hydrochloric acid. neutralisation Calderglen High School

  18. answer What is formed when a basedissolves in water? 17 An alkali Calderglen High School

  19. 18 answer What happens to thepHof an acid when diluted with water? Itincreases towards 7 Calderglen High School

  20. 19 answer What happens to the pH of an ALKALI when diluted with water ? Itdecreasestowards7 Calderglen High School

  21. 20 answer What happens to the acidity of an acid when dilutedwith water ? The acidity decreases (less acidic) Calderglen High School

  22. 21 answer What happens to thealkalinityof an alkali when diluted with water? It decreases -becomes less alkaline Calderglen High School
