titration

titration
Zelfstandig naamwoord
  • titratie, titrage
  • a measured amount of a solution of unknown concentration is added to a known volume of a second solution until the reaction between them is just complete; the concentration of the unknown solution (the titer) can then be calculated

Voorbeeldzinnen

  1. Calculation for titration according to 5.3.2
  2. the detection of biomarker and the titration of vaccine baits;
  3. Titration may also be carried out by potentiometry.
  4. The pH end-point of the titration is reached at pH 4,6, being the steepest point in the titration curve (inflection point).
  5. is the volume (ml) of NaOH (3.10 or 3.11) used in the sample titration,
  6. This can be done automatically using a steam distiller with automatic titration.
  7. ml of ammonium thiocyanate solution 0,1 mol/l used for titration
  8. Titrate with sodium thiosulphate solution (3.9) until a dull yellow colour appears, add the starch indicator (3.10) and complete titration.
  9. Where titration of the ammonia content of the distillate is performed manually, the procedure mentioned below applies.
  10. Where the distillation unit is fully automated to include titration of the ammonia content of the distillate, follow the manufacturer's instructions for operation of the distillation unit.
  11. Where a fully automatic distillation unit is employed, the automatic titration of the ammonia can also be carried out with end-point detection using a potentiometric pH system.
  12. Carry out the analysis (digestion, distillation and titration) on 1,5 to 2,0 g of acetanilide (3.13) in the presence of 1 g of sucrose (3.14); 1 g acetanilide consumes 14,80 ml of sulphuric acid (3.5).
