Other Safety Measures:

  • Hair tied back at all times.
  • Any spillages reported and cleaned up appropriately.
  • Protective gloves.
  • No loose clothing (wear a lab. coat).
  • Be aware of other peoples’ equipment and that they may be filling a burette at floor-level (ie. don’t trip over them!).
  • Let other people know what substances you are working with, especially in the communal fume cupboard.

Measures to Increase Accuracy:

Calculating The Oxidation States of The Vanadium Ions:

In Method 1:

  • 25.00cm3 of 0.02molar ammonium vanadate contains 0.0005moles of vanadium ions. ...
