What is Manganese Carbonate?
Manganese Carbonate is an inorganic compound appearing as a pink to brownish-pink powder. It is insoluble in water but soluble in dilute acids. The compound occurs naturally as the mineral rhodochrosite and is an important source of manganese for various industrial applications. It decomposes upon heating to manganese oxide and carbon dioxide.
