Voorbeeldzinnen

1. Cool immediately in cold water and after approximately five minutes titrate as follows:
2. Titrate the excess dichromate by adding to it the iron (II) ammonium sulphate solution (paragraph 3.2).
3. ‘Titrate with 0,05 mol/l iodine (I2) solution in the presence of a starch solution as an indicator.
4. Titrate with sodium thiosulphate solution (3.9) until a dull yellow colour appears, add the starch indicator (3.10) and complete titration.
5. Dilute with 100 ml of water then titrate the liberated iodine with sodium thiosulphate (0,1 N) in the presence of starch TS [2].
6. Titrate the excess silver nitrate with the ammonium thiocyanate solution (3.1) until the reddish-brown tint has lasted for one minute.
7. Titrate the excess dichromate by adding to it the iron (II) ammonium sulphate solution (paragraph 3.2). Stop adding the ferrous solution when the mixture changes from green-blue to brown.
8. Titrate the contents of the collecting flask with the hydrochloric acid standard volumetric solution (3.19) or with the sulphuric acid standard volumetric solution (3.6) using a burette and read the amount of titrant used.
9. Dissolve 1 g of the sample, weighed to the nearest mg, in the heated solution, and titrate with 0,1 N KMnO4 to a pink colour that persists for 15 seconds. Not more than 0,5 ml should be required
10. Dissolve 1 g of the sample, weighed to the nearest mg, in the heated solution, and titrate with 0,1 N KMnO4 to a pink colour that persists for 15 seconds.
11. Place 10 ml of this solution in a round-bottomed flask containing 250 ml of iodine solution, add 15 ml of water and 3 g of potassium iodide; leave the mixture to stand for 15 minutes. Dilute with 100 ml of water then titrate the liberated iodine with sodium thiosulphate (0,1 N) in the presence of starch TS [2].
12. Titrate the positive control sera in a twofold dilution series, from 1 in 5 to 1 in 640, across column 1 in blocking buffer (PBS containing 0,05 % (v/v) Tween-20, 5,0 % (w/v) skimmed-milk powder (Cadbury’s MarvelTM) and 1 % (v/v) adult bovine serum) to give a final volume of 50 μl/well.
