Part 2 – solubility of cerium(IV) sulphate in sulphuric acid
In addition to the standard apparatus present in a laboratory you are provided with the
following materials.
5 mol dm–3 sulphuric acid
distilled water
solid cerium(IV) sulphate
Give a step-by-step description of how you would prepare a range of solutions of
sulphuric acid of different concentrations. These solutions could then be used to
investigate the solubility of cerium(IV) sulphate in different concentrations of sulphuric
acid. See section (e).
Your plan should include details of the following.
(i) the number and concentrations of the solutions to be prepared
(ii) the volumes of acid and water used to prepare the solutions
(iii) the apparatus and method you would use in their preparation

Can anyone please tell me how would we make different concentrations of H2So4. as in what volumes of water and acid could be used it says in MS that 60cm3 should be the vol of acid used?? it is )/n 08 q1

How do we know when to draw a line and when to draw curve? May 2013 says to draw a line of best fit but we are supposed to draw a curve as the MS says.

 

[TANJIAHOU]

A line of best fit can be a line or a curve.

 

[scouserlfc]

How do we know when to draw a line and when to draw curve? May 2013 says to draw a line of best fit but we are supposed to draw a curve as the MS says.

Just check out if the points are coming on a line if they are then well and good and if not see if u have a general curved pattern involving your points if it's there draw the curve and not line and make sure curve is smooth and does not deviate to allow even points that wud not be on line.
