QUANTITATIVE (PART 2)

1.    calculate the concentration of a solution in mol/dm3 given the mass of solute and volume of solution;
2.    calculate the number of moles or mass of solute in a given volume of solution of known concentration;

3.    demonstrate knowledge and understanding that the volumes of acid and alkali solutions that react together can be measured by titration using phenolphthalein or methyl orange;

4.    carry out acid-base titrations using an indicator and record results to one decimal place, repeating for reliability and calculating the average titre from accurate titrations (details of the practical procedure and apparatus preparation are required); and5.    collect data from primary and secondary sources for acid-base titration and use this data to calculate the concentrations of solutions in mol/dm3 and g/dm3.

6.    calculate concentrations of solutions and solution volumes in an acid-base titration, identify unknown compounds and determine the degree of hydration

7. Recall that the volume of one mole of any gas at room temperature and pressure (20°C and 1 atmosphere pressure) is 24 dm3;

8. Recall and use Avogadro's Law as equal volumes of gases at the same temperature and pressure contain the same number of particles/molecules;

9.    calculate the volumes of gaseous reactants and products from the balanced equation for a reaction;1

0.    calculate the atom economy of a reaction to form a desired product from the balanced equation:

11.    demonstrate knowledge and understanding that a high atom economy is important for sustainable development and economic reasons;•

determine the reacting volumes of solutions of acid and alkali by titration and determine the concentration of solutions of acid and alkali by titration.
