Pyro HiD

o!
super...
ale jak podzielić na 10 części 1 gram bromku potasu ???

nie trzeba, po pirokatechinie rozpuszczasz fenidon
acha jeszcze jedno, podziel wszystkie odczynniki na 10 i rozpuszczaj w 100ml

no to ja zgłupiałem...

MIXING THE STOCK SOLUTIONS

Stock Solution A

1. Start with 750ml of distilled water.
2. Add 10g of sodium metabisulfite and stir until dissolved.
3. Add 50g of Pyrocatechin and stir until dissolved.
4. Mix 2.0g of Phenidone with about 5ml of isoprophyl alcohol and stir into an even paste, then add to the stock solution and stir until dissolved.
5. Add 1.0g of potassium bromide and stir until dissolved.
6. Add distilled water to 1000ml.

Stock Solution B

1. Start with 700ml of distilled water.
2. Weigh out 750g of potassium carbonate* and add the chemical very slowly to the water, with constant and rapid stirring. If you add the solution too fast, or don’t stir enough, it will be impossible to dissolve all of it in the water. As you add the chemical an exothermic reaction takes place and the solution will warm up appreciably.
3. Add distilled water to 1000ml.
* Potassium carbonate is deliquescent, which means that it will absorb water from the air. It must be stored in sealed containers to prevent this from happening because if you weigh out 100g of potassium carbonate that has absorbed a lot of water the actual chemical weight might be only 60-80g, which of course would produce a much weaker B solution than the formula requires.


w punkcie czwartym stoi jak byk, że 2 gramy Fenidonu rozmieszać w 5 ml izopropanolu...

do czego Ci isopropanol ?

zmieniłeś utrwalacz na coś mocniejszego? booosz...
