(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

Covalent Bonding - Save My Exams

Oxygen atoms form both covalent and ionic bonds. (a) Water is formed when two atoms of hydrogen combine with one atom of oxygen. (i) Draw a dot and cross diagram of a molecule of water. You need only show the electrons in the outer shells. (2) (ii) Explain how the covalent bonds in the water molecule hold the hydrogen and oxygen atoms together. (2)

The deflection can be monitored by a strain gage such that voltage output is p across diaphragm, which enables electronic data acquisition with computers. In this course we will use both manometers and pressure

The Oscilloscope: Operation and Applications

The deflection, due to an applied voltage, can be measured with the aid of the calibrated lines on the graticule. First we will consider the circuitry that amplifies and conditions the voltage to be measured (the “Amp” block in figure 1). The deflection of the oscilloscope beam is proportional to the input voltage (after ac or dc coupling).
