Magnesium sulphate (large granular) Magnesium sulfate (or magnesium sulphate, Epsom salt ,Bitter salt ) is a chemical compound containing magnesium ,sulfur and oxygen,with the formula Mgso4. In its hydrated form ,the PH is 6.0(5.5-6.5).It is often encountered as the heptahydrate ,Mgso4·7H2O, commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent .Since the anhydrous form is hygroscopic (readily absorbs water from the air )and is therefore difficult to weigh accurately, the hydrate is often prefered when reparing solutions ,for example ,in medical preparations ,Epsom salt has been traditionally used as a component of bath salts . In agriculture and gardening ,magnesium sulfate is used to correct magnesium derficiency in soil ,since magnesium is an essential element in the chlorophyll molecule. It is the commonly applied to potted plants ,or to magnesium-hungry crops ,such as potatoes ,roses ,tomatos ,peppers amd cannbis. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic line )is its high solubility. In Medical use,magnesium sulfate can be used as the replacement therapy for hypomagnesemia. And it is the first-line antiarrhythmic agent for torsades de points in cardiac arrest under 2005Ecc guidelines and for managing quinidine induced arrhythmias. Recent studied have revealed that magnesium sulfate can be nebulized to rduce the symptoms of acute asthma. It is commonly adminisrered via the intravenous route for the management of severe asthma attacks. Magnesium sulfate, when used through soaking, can soothe muscle pains and help improve rough patches in the skin Appearance Colorless,crystal,odorless Main content % ≥99.5% Mgso4 ≥48.59% Mgo ≥16.24% Mg ≥9.8% PH 5----------9 Ferric salt% ≤0.0015% Chloride% ≤0.015% Heavy metal% ≤0.0008% Arsenic salt% ≤0.0005% Clarity Transparent Weight lost on ignition% 48.0-52.0
