A list of “learning outcomes” for the topic is shown below. When the topic is complete you should review each learning outcome. You are expected to consult your teacher if you have any issues with the learning outcomes. State that a standard solution is a solution of known concentration Know how to weigh chemicals by the weighing by difference method. that a solution may be standardised by using a primary standard. State the properties required of a primary standard. Be able to name some primary standards. that sodium hydroxide is not a primary standard and state reasons why. the procedure required to prepare a standard solution. Be able to out simple uncertainty calculations and be aware of the uncertainties in laboratory equipment. State that a control experiment allows the validity of a technique to be evaluated and to be able to suggest chemicals which can be used as controls. State that volumetric analysis involves measuring volumes and the main technique is titration. Sate what a back titration is and state the reasons it may be necessary to carry out a back titration. State that gravimetric analysis involves weighing reactants and products. Be able to explain what is meant by heating to constant mass. State that colorimetry can be used to analyse the concentration of coloured solutions. State that when carrying out a colorimetric analysis the filter which provides maximum absorption for the test substance is always chosen
