Audited Supplier | Physical and chemical properties: purple or purple red equiaxed crystal octahedral crystal, easy to make large particle crystal. The relative density is 1.826 (25 ° C). Melting point is 89 ºC. When heated to 100 ° C, it loses 10 crystal water, and when heated to 400 ° C, it loses 12 crystal water and becomes anhydrous. Soluble in water, dilute acid, insoluble in alcohol. It dissolves in water and is a purple-red aqueous solution. It turns to a green solution when heated to 70 ° C, and gradually turns purple after cooling. It absorbs moisture easily and can be weathered in dry air. Molecular formula: KCr (SO4) 2-12H2O Usage: Used as tanning agent, mordant and photographic fixing agent, etc. |
| Packing: Packed in plastic woven bag lined with polyethylene plastic bag, net weight 25kg per bag. |
| It should be stored in a cool, ventilated and dry warehouse. The packaging should be sealed, pay attention to moisture and weathering. Do not store and transport with edible items, flammable items and acids. During transportation, it is necessary to prevent rain and sun exposure. Handle with care when handling to prevent damage to the packaging. In case of fire, use water, sand and carbon dioxide fire extinguishers to extinguish. |
