Manganese dioxide In another process manganese dioxide is carbothermically reduced to manganese(II) oxide which is dissolved in sulfuric acid. The filtered solution is treated with ammonium carbonate to precipitate MnCO. 3. The carbonate is calcined in air to give a mixture of manganese(II) and manganese(IV) oxides. To complete the process, a suspension of this material in sulfuric acid is treated with sodium chlorate. Chloric acid, which forms in situ, converts any Mn(III) and Mn(II) oxides to the dioxide, releasing chlorine as a by-product. A third process involves manganese heptoxide and manganese monoxide.

Water Problems â Manganese Manganese is present most frequently as a manganous ion (Mn++) in water. Salts of man­ganese are generally more soluble in acid than in alkaline water. In this way they are similar to iron. The manganous ion is usually introduced to water through the solubility of manganous bicarbonate.

Sulfide Sulfide (systematically named sulfanediide, and sulfide(2−)) is an inorganic anion of sulfur with the chemical formula S 2− .It contributes no color to sulfide salts. As it is classified as a strong base, even dilute solutions of salts such as sodium sulfide (Na 2 S) are corrosive and can attack the skin.issolved free sulfides (H 2 S, HS − and S 2−) are very aggressive species for the corrosion of many metals such as steel, stainless steel, and copper. Sulfides present in aqueous solution are responsible for stress corrosion cracking (SCC) of steel, and is also known as sulfide stress cracking.

- When the water travels through the pipes those minerals precipitate on to the surface of the pipes or onto soilds that have already precipitated. The minerals could be iron oxide (rust is one form) but it could be a lot of other things too. Magnesium, calcium, iron are common cations and carbonate, sulfate, and hydroxide are common anions. So it could be calcium carbonate (chalk) in your pipes.

caustic 1 They are precipitated from their alkaline solutions as cobalt sulphide by sulphuretted hydrogen, but this precipitation is prevented by the presence of citric and tartaric acids; similarly the presence of ammonium salts hinders their precipitation by caustic alkalis.

Treating Manganese in Well Water Precipitated manganese is easily removed by a filter, but it is not removed well by a water softener. It is important to understand that a water softener is an ion exchanger. It deals with un-precipitated ions. Filters can't remove manganese or iron in their un-precipitated state.

Effects of Mn, P, S, Si & V on the Mechanical Properties of Steel For welding, weldability decreases with increasing sulphur content. Sulphur is detrimental to surface quality in low carbon and low manganese steels and it promotes hot shortness in welding with the tendency increasing with increased sulphur.n welding, silicon is detrimental to surface quality, especially in the low carbon, resulphurized grades. It aggravates cracking tendencies when the carbon content is fairly high. For best welding condition, silicon content should not exceed 0.10%.

- General guidelines for Manganese application. Persistent, severe manganese deficiency reduces cropping, growth and yield. Manganese is involved with photosynthesis, efficient use of N, protein metabolism and enzyme activation. Both soil application and foliar sprays increase yields in deficient trees. This is mainly as a result of increasing the number of fruit per tree.

Sulfuric acid Sulfuric acid is formed naturally by the oxidation of sulfide minerals, such as iron sulfide. The resulting water can be highly acidic and is called acid mine drainage (AMD) or acid rock drainage (ARD).This acidic water is capable of dissolving metals present in sulfide ores, which results in brightly colored, toxic streams.he resulting water can be highly acidic and is called acid mine drainage (AMD) or acid rock drainage (ARD).

Precipitation Reactions of Hydrated Ions Cross-combinations give soluble salts. The rule that all nitrates are soluble falls into this category. Rule #4.The solubility of feebly basic anions such as sulfate are difficult to predict. The tendency of these salts to precipitate or not precipitate varies with the relative magnitude of the opposing entropy and enthalpy terms

Sulfate, Hydrogen Sulfide, Sulfate Reducing Bacteria - How to Identify and Manage Sulfur-reducing bacteria, which use sulfur as an energy source, are the primary producers of large quantities of hydrogen sulfide. These bacteria chemically change natural sulfates in water to hydrogen sulfide.Sulfur-reducing bacteria live in oxygen-deficient environments such as deep wells, plumbing systems, water softeners and water heaters.ulfur-oxidizing bacteria produce effects similar to those of iron bacteria. They convert sulfide into sulfate, producing a dark slime that can clog plumbing and/or stain clothing. Blackening of water or dark slime coating the inside of toilet tanks may indicate a sulfur-oxidizing bacteria problem.

Hydrogen sulfide Hydrogen sulfide often results from the bacterial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion. H 2S also occurs in volcanic gases, natural gas, and in some sources of well water.ydrogen sulfide is slightly soluble in water and acts as a weak acid, giving the hydrosulfide ion HS − (pKa = 6.9 in 0.01-0.1 mol/litre solutions at 18 °C). A solution of hydrogen sulfide in water, known as sulfhydric acid or hydrosulfuric acid, is initially clear but over time turns cloudy.

Soil Acidity Subsoil Acidity. Even if the top 6 inches of soil show a pH above 6.0, the subsoil may be extremely acidic. When subsoil pH's drop below 5.0, aluminum and manganese in the soil become much more soluble, and in some soils may be toxic to plant growth.

- Hydrogen sulfide is a colorless gas that can exist naturally in groundwater. Sulfur-reducing bacteria present in groundwater use sulfur as an energy source to chemically change sulfates to hydrogen sulfide. The bacteria use sulfur from decaying plants and other organic matter in oxygen-deficient environments.

Chemistry Lab Preparation of Soap? The soap interacted with the calcium and magnesium to form insoluble salts (soap scum). The iron doesn't bond well with the soap, but it is highly soluble in the water making a yellow solution.Tap water (hard water in particular) contains a lot of magnesium and calcium (usually from carbonate sources at the water table).These met with your soap and formed the same precipitates... though in lower concentrations.ap water (hard water in particular) contains a lot of magnesium and calcium (usually from carbonate sources at the water table).
