Voorbeeldzinnen

1. Titrate the liberated iodine with sodium thiosulphate (0,1 N) in the presence of starch TS [2].
2. Cool immediately in cold water and after approximately five minutes titrate as follows:
3. Titrate the excess dichromate by adding to it the iron (II) ammonium sulphate solution (paragraph 3.2).
4. Titrate with sodium thiosulphate solution (3.8) until a dull yellow colour appears, add the starch indicator (3.9) and complete titration.
5. Using a microburette (4.3), titrate the volatile bases in the boric acid solution with sulphuric acid (3.5).
6. Boil for exactly 10 minutes. Cool immediately in cold water and after approximately five minutes titrate as follows:
7. ‘Titrate with 0,05 mol/l iodine (I2) solution in the presence of a starch solution as an indicator.
8. Titrate with sodium thiosulphate solution (3.9) until a dull yellow colour appears, add the starch indicator (3.10) and complete titration.
9. Dissolve 1 g of potassium lactate solution in 20 ml of water, add 3 drops of phenolphthalein TS and titrate with 0,1 N sodium hydroxide.
10. After the precipitate is completely dissolved, titrate the liberated iodine with sodium thiosulphate (0,1 N) in the presence of starch TS [2].
11. Titrate the acidity in the effluent (including the rinse water) with the 0,1 M sodium hydroxide solution until the pH is 7 at 20 °C.
12. Dilute with 100 ml of water then titrate the liberated iodine with sodium thiosulphate (0,1 N) in the presence of starch TS [2].
13. Titrate the excess silver nitrate with the ammonium thiocyanate solution (3.1) until the reddish-brown tint has lasted for one minute.
14. Titrate the excess sulphuric acid in the collecting flask with sodium hydroxide solution (3.10 or 3.11) depending on the concentration of the sulphuric acid used, until the end-point is reached.
15. Dissolve 1 g of potassium lactate solution in 20 ml of water, add 3 drops of phenolphthalein TS and titrate with 0,1 N sodium hydroxide. Not more than 0,2 ml should be required
