Acids, Bases and Neutralisation
Cards in this deck (15)
- 1All acids containhydrogen
- 2When an acid is dissolved in water it does what?Releases H+ ions into the solution
- 3Strong Acid- Fully Dissociates
- Releases all its H atoms into solution as H+ ions
-Example: HCl - 4Weak Acid- Partially Dissociates
- Releases only a small proportion of its available H atoms as H+ ions in solution
- Example: CH3COOH - 5Bases - definitionA base neutralises an acid to form a salt
- 6Bases - Examples- Metal Oxide
-Metal Hydroxide
- Metal Carbonate
- Ammonia (NH3) - 7Alkali - DefinitionAn alkali is a base that dissolves in water releasing hydroxide ions (OH-) into the solution. An example of a base/alkali is sodium hydroxide.
- 8Neutralising an acid with a baseH+ ions react with a base to form a salt and neutral water. H+ ions from the acid are replaced by metal or ammonium ions from the base.
- 9Acid + Alkali -->salt + water
- 10Ionic Equation for neutralisationH+ + OH- --> H2O
- 11Acid + Metal Oxide -->Metal Salt + Water
- 12Acid + Metal Hydroxide -->Metal Salt and Water
- 13Neutralisation of sulphuric acid with Copper (II) Oxide =sulphuric acid + Copper (II) Oxide --> Copper sulphate + Water
H2SO4 (aq) + CuO (s) --> CuSO4 (aq) + H2O (l) - 14Acid + Metal Carbonate -->Metal Salt + Water + Carbon Dioxide
- 15Neutralisation of Zinc Carbonate with Sulphuric AcidZinc Carbonate + Sulphuric Acid --> Zinc Sulphate + Water + Carbon Dioxide
ZnCO3 (s) + H2SO4 (aq) --> ZnSO4 (aq) + H2O (l) + CO2 (g)
