3.picture presentation
4.application of magnesium sulphate heptahydrate :
①In agriculture and gardening , magnesium sulfate is used to correct magnesium deficiency in soil ( magnesium is an essential element in the chlorophyll molecule ) .
②Feed-grade magnesium sulfate as feed processing magnesium supplements .
③Industry for tanning , fertilizer , paper , porcelain , printing dyes , lead-acid battery industry .
5.performance:
White fine acicular or inclined columnar crystal.Odorless, bitter taste, easy weathering in dry air.The proportion of 1.68.Soluble in water, slightly soluble in alcohol and glycerin.The crystallization of the water in the 67.5℃ dissolve in itself.Thermal decomposition, 70, 80℃ is lost four molecules of crystal water.In 200℃ lost all crystallization water into magnesium sulphate.
