(e) The sulfur dioxide content of wine is most commonly measured by the Ripper Method which involves titration with iodine in the presence of starch as an indicator. SO 2 (aq) + I 2 (aq) + 2H 2 O(l) → 2I –(aq) + SO 4 2–(aq) + 4H+(aq) 3A 50.0 cm sample of wine required 12.35 cm3 of 0.010 mol dm–3 I 2 (aq) for complete reaction with the SO 2.

Mark Scheme (Results) Summer 2019

Where some judgement is required, mark schemes will provide the principles by which marks will be awarded and exemplification may be limited. When examiners are in doubt regarding the application of the mark scheme to a candidate’s response, the team leader must be consulted. Crossed out work should be marked UNLESS the candidate

Figure 1-3 - Location of the poles of a second-order system in the complex frequency plane. It is of interest to us to plot the locus of the poles, p1 and p2, as Q is varied from 0 to ∞. The resulting plot is called a root locus plot and is shown in Fig. 1-4. There are two loci on this plot, one corresponding to p1 and the other to p2. At Q=0 ...
