Spelling note: sulphuric acid = sulfuric acid, sulphate = sulfate, aluminium = aluminum (US) You must know four general word equations, all of which involve neutralisation (Foundation or Higher students) and higher students would be expected to write and interpret them as symbol equations too. (i) is also a redox reaction. (i) metal + acid ==> a salt + hydrogen (ii) basic oxide or hydroxide + acid ==> a salt + water (iii) carbonate + acid ==> a salt + water + carbon dioxide (iv) ammonia + acid ==> ammonium salt (note: no water formed, but ammonia (NH3) is an alkaline gas and soluble in water and neutralised by acids to form ammonium salts (NH4 ...) The name of the salt depends on (i) the metal name, which becomes the first part of salt name, and (ii) the acid e.g. H2SO4 sulfuric acid makes a ... sulfate (...SO4), HCl hydrochloric acid makes a ... chloride (...Cl), HNO3 nitric acid makes a … nitrate (...NO3) and CH3COOH ethanoic acid makes an ethanoate (...OOCCH3 or CH3COO..). 1a WORD EQUATION QUESTIONS (just write down Q number plus space answers and check) (you might have to fit two words in a line space) 1. zinc + hydrochloric acid ===> ___________________________ + hydrogen 2. _______________________ + sulfuric acid ===> copper(II) sulfate + water + carbon dioxide 3. magnesium oxide + ___________________________ ===> magnesium nitrate + water 4. zinc + sulfuric acid ===> zinc sulfate + ___________________________ 5. magnesium hydroxide + hydrochloric acid ===> ___________________________ + water 6. __________________ + nitric acid ===> copper(II) nitrate + water + __________________ 7. zinc carbonate + sulfuric acid ===> ______________ + ____________ + carbon dioxide 8. iron + ___________________________ ===> iron(II) chloride + hydrogen 9. magnesium oxide + hydrochloric acid ===> ____________________ + ________________ 10. _________________ + hydrochloric acid ===> calcium chloride + water + __________________ 11. ___________________________ + sulfuric acid ===> magnesium sulfate + hydrogen 12. magnesium + nitric acid ===> ___________________________ + hydrogen 13. zinc hydroxide + ___________________________ ===> zinc chloride + water 14. ____________________ + hydrochloric acid ===> magnesium chloride + water + carbon dioxide 15. aluminium + hydrochloric acid ===> ___________________________ + hydrogen 16. sodium hydroxide + hydrochloric acid ===> _______________________ + ________________ 17. sodium carbonate + _________________ ===> sodium sulfate + water + ________________ 18. ___________________________ + nitric acid ===> calcium nitrate + water + carbon dioxide 19. ___________________________ + sulfuric acid ===> iron(II) sulfate + hydrogen 20. zinc oxide + ___________________________ ===> zinc chloride + water 21. copper(II) carbonate + sulfuric acid ===> _____________________ + water + carbon dioxide 22. aluminium + ___________________________ ===> aluminium sulfate + hydrogen 23. calcium oxide + hydrochloric acid ===> ______________________ + _________________ 24. magnesium hydroxide + ________________ ===> magnesium sulfate + ________________ 25. ammonia + sulfuric acid ===> ___________________________ 26. ammonia + ___________________________ ===> ammonium chloride 27. zinc hydroxide + sulfuric acid ===> _____________________ + ______________ 28. copper(II) oxide + hydrochloric acid ===> ___________________________ + water 29. sodium hydroxide + sulfuric acid ===> ___________________________ + water 30. sodium hydrogencarbonate + hydrochloric acid ===> ________________ + _________________ + ________________ 31. ammonia + ___________________________ ===> ammonium nitrate 32. calcium oxide + _____________________ ===> calcium chloride + _____________________ 33. aluminium hydroxide + nitric acid ===> ___________________________ + water 34. calcium carbonate + ________________ ===> calcium ethanoate + ____________ + ________________ 35. ethanoic acid + magnesium ===> ____________________ + hydrogen 36. _________________ + magnesium oxide ===> magnesium ethanoate + ____________ 37. sodium hydroxide + _______________ ===> _____ ethanoate + _____________
