Raw Materials | Iodine Potassium chlorate Nitric acid Potassium nitrate |
colorless rhombic or monoclinic crystals. Soluble in water, the solution is acidic. Insoluble in ethanol. In case of reducing material decomposition, and precipitation of iodine and make it pink to purple. Mixed with organic matter, reducing agent, sulfur, phosphorus, etc. Become an explosive mixture. Strong corrosion
Industrial potassium chlorate is dissolved in water at a certain temperature, hydrochloric acid is added and iodine is added immediately, and potassium chlorate can be added to discolor the yellow color therein. Stand still and crystallize.
Common analytical reagents. The baseline of the base was calibrated.
Toxic; Corrosive. Staff should be well protected, if accidentally touch the eyes, should immediately rinse with a large amount of flowing water. The working environment should have good ventilation conditions. Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat source. Packaging is required to be sealed and not to be in contact with air. Avoid light. Should be stored separately from the reducing agent, flammable, combustible, etc.
