Chemistry 1.4 Describe characteristic properties and reactions of metals, acids and bases
Achievement criteria
The level of achievement that you will reach is decided by the way you answer each question. The key words are describe, explain, and apply aspects of characteristic properties and reactions of metals, acids, and bases.
Achievement
Make sure you can:
- Describe characteristic properties and reactions of metals, acids, and bases.
- write word equation
- identify reaction types from given equations
- write correct formulae of reactants and/or products in a given equation
- describe observations of reactions
- describe physical and/or chemical properties of metals relevant (or not) to a specified use
- link correct colours of indicators with acidic, alkaline, or neutral solutions
- define a neutralisation reaction
- identify factors that increase/decrease rate of reaction.
Achievement with Merit
Make sure you can:
- Explain characteristic properties and reactions of metals, acids, and bases.
- link observations to the correct chemical species
- select appropriate properties of a metal(s) when explaining suitability for a purpose
- explain how to change the rate of a reaction specific to a given reaction
- link ease of extraction of an element to its place in the activity series
- relate electron configuration to chemical stability.
Achievement with Excellence
- Apply an understanding of characteristic properties and reactions of metals, acids, and bases.
- link observations to the correct chemical species
- select appropriate physical and chemical properties of a metal(s) when discussing suitability for a purpose
- write balanced molecular and ionic equations.
- apply particle theory to explain factors affecting rate of reaction
- demonstrate a clear understanding of relevant terms such as corrode, neutralisation, and react
- write logical, detailed answers
- justify classification of reactions using equations and/or observations
- interpret the activity series and apply it to discussing differences in metal reactions.
