  1. Bases S2 Chemistry Classifying chemicals and chemical reactions

  2. Bases • A base is a substance which reacts with an acid to produce water. • The three types of base are: • metal oxides • metal hydroxides • metal carbonates

  3. Bases Alkalis

  4. Nitrogen dioxide Potassium carbonate Sodium oxide Potassium oxide Sodium Calcium hydroxide Iron carbonate Hydrogen oxide Silicon oxide Sodium hydroxide Magnesium bromide Sodium chloride

  5. Nitrogen dioxide Potassium carbonate Sodium oxide Potassium oxide Sodium Calcium hydroxide Iron carbonate Hydrogen oxide Silicon oxide Sodium hydroxide Magnesium bromide Sodium chloride

  6. Salts S2 Chemistry Classifying chemicals and chemical reactions

  7. Copper nitrate Potassium carbonate Sodium oxide Potassium oxide Sodium Calcium hydroxide Iron sulphate Silicon dioxide Silicon oxide Sodium hydroxide Magnesium ethanoate Sodium chloride

  8. Copper nitrate Potassium carbonate Sodium oxide Potassium oxide Sodium Calcium hydroxide Iron sulphate Silicon dioxide Silicon oxide Sodium hydroxide Magnesium ethanoate Sodium chloride

  9. A salt is a substance made by neutralising an acid with a base. For example: calcium sulphate From base: From acid: calcium hydroxide sulphuric acid calcium oxide calcium carbonate LO: Be able to name the salt produced in reactions involving acids.

  10. Different acids produce different types of salt. Reminder: metal chlorides metal sulphates hydrochloric acid metal nitrates sulphuric acid nitric acid LO: Be able to name the salt produced in reactions involving acids.

  11. Complete the following equations: nitric acid lithium nitrate ? + + water nickel oxide sulphuric acid ? nickel sulphate + + water iron oxide hydrochloric acid iron chloride ? + + water calcium hydroxide ? sulphuric acid calcium sulphate + + water magnesium oxide ? nitric acid magnesium nitrate + + water LO: Know the characteristic reactions of acids with bases. lithium hydroxide

  13. Neutralisation S2 Chemistry Classifying chemicals and chemical reactions

  14. Neutralisation is the reaction of acids with Metal , bases water A neutralisation reaction always produces as a product. Neutralisation: up to 7 • moves the pH of an acid . down to 7 • moves the pH of an alkali . Bases include: oxides hydroxides • Metal , carbonates • Metal , alkali A base that dissolves in water forms an . LO: Understand what a neutralisation reaction is.
