Zinc sulfate monohydrate
Pure zinc sulfate in the air for a long time without yellow, placed in dry air to lose water and become white powder. There are many kinds of hydrates: in the range of 0-39 ℃, the hydrate is zinc sulfate heptahydrate, 39-60 ℃ is zinc sulfate hexahydrate, and 60-100 ℃ is zinc sulfate monohydrate. Pure zinc sulfate in the air for a long time without yellow, placed in dry air to lose water and become white powder.
Zinc sulfate heptahydrate
Magnesium sulfate 0.1-1mm
White or colorless crystals, odorless, cool and slightly bitter, soluble in water, slightly soluble in ethanol, in the air (dry) easily weathered into powder, heating gradually remove the crystal water into anhydrous magnesium sulfate.
Magnesium sulfate 1-3mm
Magnesium sulfate 3-4mm
Magnesium sulfate 4-7mm
Anhydrous manganese sulfate is a nearly white orthorhombic crystal with a density of 3.25g / cm3 and a melting point of 700 ℃. Manganese sulfate monohydrate is a light pink monoclinic crystal with a density of 2.95 g/ml(25 ℃), a melting point of 700 ℃ and a boiling point of 850 ℃. Unstable under hanging temperature and normal pressure.
Anhydrous sodium sulfite
Appearance is a glossy white powder, with sulfurous acid odor, exposed to the air is gradually oxidized to sodium carbonate. Soluble in water, the solution is alkaline and can dissolve sulfur. Slightly soluble in alcohol, no change in dry air.
