This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese. Manganese dioxide is a compound of manganese(IV) with the formula MnO2. Avoid storing the oxide in metal containers, especially steel, as it will rust the metal. But you have gone from Mn IV to Mn II. Clean Air Act: CAS# 1313-13-9 (listed as Manganese compounds, n.o.s.)

EC Number: 215-202-6. 77, No. Manganese dioxide (MnO2) is a common form of Mn (IV). Soluble in HCl. Reaction of manganese with nitric acid- 3 Mn + 8 HNO3 = 3 MnNO32 + 2 NO + 4 H2O When manganese reacts with nitric acid forms manganese(II) nitrate, nitric oxide and water. Hazard to Others. Physical Data: mp 535 °C (dec.);d 5.03 g cm −3. The commercial ‘active’ MnO 2 used as oxidizing reagent for organic synthesis is a synthetic nonstoichiometric hydrated material. Manganese(II) sulfate is a metal sulfate in which the metal component is manganese in the +2 oxidation state. Manganese Dioxide is a highly insoluble thermally stable Manganese source suitable for glass, optic and ceramic applications. This material contains Manganese dioxide (listed as Manganese compounds, n.o.s. It is easy to obtain in this way, but it is very low grade. It contains a manganese… Special hazards arising from the substance or mixture Manganese/manganese oxides. Manganese dioxide is a brown to black solid which is insoluble in water. ... Solubility in water: none. Mn forms compounds in the environment with chemicals such as oxygen, sulfur (S), and chlorine, to become water soluble; examples of Mn compounds are manganese dioxide (MnO 2), manganese tetraoxide (Mn 3 O 4), Mn salts (chloride, sulfate, carbonate, and nitrate), Mn silicate, and potassium permanganate (KMnO 4). Its chemical formula is MnO 2. 1.3 Details of the supplier of the safety data sheet Company : Central Drug House (P) Ltd 7/28 Vardaan House New Delhi-10002 INDIA Different grades of Manganese Dioxide (MnO2) are manufactured ranging from MnO2 60% to 90% in powder as well as granular form. Purification from crude, battery-grade sludge was done by NurdRage by utilizing equilibria. InChI=1S/Mn.2O Manganese(II) forms numerous complexes with various anions (Cotton and Wilkinson 1980, Wiberg 1985). Manganese dioxide can be toxic to wildlife, so it's best to take it to disposal facilities. It is a common precursor to many manganese compounds, as it is easy to acquire. This source of MnO2 is still useful for many applications. Actually the solubility appears to be much in excess of the amounts normally found in natural water, The reaction also releases the halogen from its respective acid as byproduct, except for hydrofluoric acid, where elemental fluorine cannot be produced. Form Supplied in: dark brown powder, widely available. It will react with hydrochloric acid to form manganese chloride, chlorine and water. Manganese Dioxide (MnO2) is used in various manufacturing processes but is highly used in the water treatment industry. Oxalic acid will also react with MnO2. This compound will not react with some acids such as. The insoluble manganese oxalate can then be calcined at high temperature to decent purity. Manganese Dioxide Created by Global Safety Management, Inc. -Tel: 1-813-435-5161 - www.gsmsds.com material.It is the responsibility of the user to comply with all applicable laws and regulations applicable to this 58 / Monday, March 26, 2012 / Rules and Regulations 02/26/2015 EN (English) 3 Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Manganese Dioxide Safety Data Sheet according to Federal Register / Vol. Manganese dioxide is a heavy metal oxide, and is reasonably toxic. It decomposes when heated above 535 °C. is listed as a hazardous air pollutant (HAP). Manganese dioxide will also react with sulfur dioxide to form manganese(II) sulfate. Cubic green crystals that are insoluble in water but soluble in acids. The potential measured by a bright platinum electrode in aerated water is generally near +0.50 volts at neutral pH. It is used as a depolarizer in alkaline batteries and Leclanche batteries. Manganese oxide is soluble in acids and ammonium chloride, and insoluble in water.
