1.1 Chemical Change
|
| |
Candidates should be able to: |
| Describe a chemical change as one in which new substances are made and as such the products have different properties from those of the starting materials. |
1.1.1 state simple chemical reactions and word equations, including formation of oxides from metals, neutralisation and displacement reactions
|
| Recall common chemical changes such as rusting and burning |
1.1.2 describe chemical reactions which are not useful, e.g. rusting
|
| |
1.1.3 outline energy changes in exothermic and endothermic reactions
|
| |
1.1.4 formulate problems and design methods for investigating the reactivity of metals (with oxygen, water and dilute acids) and the reactivity series and examples of displacement reactions
|
| |
1.1.5 describe neutrality, acidity and alkalinity the and use of indicators and the pH scale
|
| |
1.1.6 describe neutralization reactions and their applications
|
| |
1.1.7 state methods for preparing common salts by reaction of metals or metal carbonates with acids
|
| Describe an experiment showing the need for both air and water to be present for rusting to occur. |
|
| |
1.1.8 formulate problems and design methods for experiments investigating the effect of concentration, particle size, temperature and catalysts on the rate of reactions
|
| |
1.1.9 interpret qualitative and/or quantitative data from experiments investigating the effect of concentration and temperature on the rate of reactions
