AQA GCSE Chemistry - C5
What are spectator ions? - ANS-Ions that do not take part in a reaction
\What are the 2 non-metals in the reactivity series? - ANS-Carbon & hydrogen
\What form do more reactive metals found in the earth take? - ANS-Minerals and ores
\What happens in partial ionisation? (weak acids) - ANS-The point of equilibrium is reached
\What happens to ionic compounds when they are dissolved in water? - ANS-They
disassociate (split up)
\What happens when a metal is reacted with oxygen - ANS-A metal oxide is formed
\What happens when a metal is reacted with water? - ANS-A metal hydroxide and hydrogen
are produced
\What is a base? - ANS-An ionic compound that can neutralise acids
\What is a carbonate? (In relation to bases) - ANS-An insoluble base
\What is a displacement reaction? - ANS-Reaction: More reactive element replaces less
reactive one
\What is a displacement reaction? - ANS-Where a more reactive metal displaces a less
reactive one
\What is a half-equation? - ANS-An equation that shows a reactant gaining/losing electrons
\What is a redox reaction? - ANS-A reaction where one reactant is oxidised, other one
reduced
\What is a salt? - ANS-A compound consisting of a metal and part of an acid
\What is an alkali? (In relation to bases) - ANS-A soluble base
\What is an ionic equation? - ANS-Equation where charges of reactants, products are
featured
\What is generally used to separate a metal from its ore using a redox reaction? -
ANS-Carbon
\What is Oxidation? - ANS-Where an atom loses electrons
\What is reduction? - ANS-Where an atom eats electrons
\What is the difference between strong and weak acids? - ANS-Strong acids ionise
completely, weak acids don't (reversible)
\What is the natural form of unreactive metals inside the earth? - ANS-Nuggets or flakes
\What is the reactivity series? - ANS-A list of elements ordered by their reactivity
\What salts does Hydrochloric acid form? - ANS-Chlorides
\What salts does Nitric acid form? - ANS-Nitrates
\What salts does sulphuric acid form? - ANS-Sulphates
\What two things can be used to measure pH? - ANS-pH probe and indicator
\When does rock with metal minerals in become an ore? - ANS-When % of minerals is high
enough to be commercially viable
\Where in the working world is salt making used? - ANS-Fertiliser
