  2. answer 1 Give an everyday example of neutralisation. Reducing acidity in soil by adding lime, treatment of acid indigestion eymmcl2003

  3. answer What is Neutralisation? 2 The reaction of an acid with a neutraliser eymmcl2003

  4. answer What happens to the pH of an acid as it is neutralised? 3 The pH INCREASES to 7 eymmcl2003

  5. answer Give some examples of neutralisers 4 Alkali, metal oxide, metal carbonate eymmcl2003

  6. answer Name the products of the reaction between a dilute acid and an alkali 5 Salt and water eymmcl2003

  7. answer Name the products in the reaction between a dilute acid and a metal carbonate. 6 Salt, water and carbon dioxide eymmcl2003

  8. answer Name the salt produced when dilute hydrochloric acid reacts with copper carbonate 7 Copper chloride eymmcl2003

  9. answer Name the products of the reaction between a dilute acid and a metal oxide 8 Salt and water eymmcl2003

  10. answer Name the products when dilute sulphuric acid reacts with magnesium 9 Magnesium sulphate and hydrogen eymmcl2003

  11. answer What is the formula forhydrochloric acid? 10 HCl eymmcl2003

  12. answer What is the formula forsulphuric acid? 11 H2SO4 eymmcl2003

  13. answer Name the products of the reaction between potassium hydroxide and dilute nitric acid 12 potassium nitrate and water eymmcl2003

  14. answer Which method is used to prepare insoluble salts? 13 precipitation eymmcl2003

  15. answer Name the precipitate formed when barium nitrate solution and sodium sulphate solution react together 14 Barium sulphate eymmcl2003

  16. answer NaOH + HNO3 NaNO3 + H2OIn a titration, 20cm3 of sodium hydroxide was neutralised by 15cm3 of 0.2 mol/l nitric acid. Calculate the concentration of the sodium hydroxide solution. 15 CVH+ (acid) = CVOH- (alkali) 0.2 x15x1 = Cx20x1 3= C x 20 C = 3/20 = 0.15 mol/l eymmcl2003
