Betekenis van:
barium hydroxide

Voorbeeldzinnen

1. Barium hydroxide
2. With age barium hydroxide becomes more difficult to dissolve.
3. Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides, of strontium or barium:
4. Add 8,4 g barium hydroxide octa-hydrate (3.4) and 10 ml water.
5. Hydroxide and peroxide of magnesium oxides; hydroxides and peroxides of strontium or barium
6. Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides, of strontium or barium
7. Add 8,4 g barium hydroxide octa-hydrate (3.4) and 10 ml water. Mix on a vortex mixer (4.8) or magnetic stirrer (4.7).
8. For the determination of the total tryptophan, the sample is hydrolysed under alkaline conditions with saturated barium hydroxide solution and heated to 110 oC for 20 hours.
9. When a stream of the sample is passed through a solution of barium hydroxide, a white precipitate is produced which dissolves with effervescence in dilute acetic acid
10. With age barium hydroxide becomes more difficult to dissolve. This results in an unclear solution for the HPLC determination, which may produce low results for tryptophan.
11. Barium hydroxide octa-hydrate (care shall be taken not to expose the Ba(OH)2 .8 H2O excessively to air in order to avoid formation of BaCO3, which could disturb the determination) (see observation 9.3).
