How to Prepare and Use
- 1In 0.7–0.8 liters of water at a temperature of about 40 °C, dissolve the contents of packets 1, 2, 3, 4, and 5 one after another while stirring—add each subsequent packet only after the previous one has completely dissolved.
- 2Package 1 — anhydrous sodium sulfite (5 g); package 2 — sodium metabisulfite (30 g); package 3 — ammonium thiocyanate (50 g); Packets 4 and 5 — crystalline sodium thiosulfate (108 g and 242 g).
- 3After all the substances have dissolved, let the solution cool to room temperature and bring the volume up to 1.0 liter.
- 4The solution can be used immediately after preparation.
