#C6.1.1
recall that acids react with some metals and with carbonates and write equations predicting products from given reactants
#C6.1.2
describe practical procedures to make salts to include appropriate use of filtration, evaporation, crystallisation and drying
PAG7
#C6.1.3
use the formulae of common ions to deduce the formula of a compound
#C6.1.4
recall that relative acidity and alkalinity are measured by pH including the use of universal indicator and pH meters
#C6.1.5
use and explain the terms dilute and concentrated (amount of substance) and weak and strong (degree of ionisation) in relation to acids including differences in reactivity with metals and carbonates
#C6.1.6
use the idea that as hydrogen ion concentration increases by a factor of ten the pH value of a solution decreases by one
#C6.1.7
describe neutrality and relative acidity and alkalinity in terms of the effect of the concentration of hydrogen ions on the numerical value of pH (whole numbers only)
