Manganese deficiency is easy to cure and homeowners have several options when treating these symptoms. The first is to adjust the soil pH. Two materials commonly used for lowering the soil pH are ammonium sulfate and sulfur. Ammonium sulfate will change the soil pH instantly because the ammonium produces the acidity as soon as it dissolves in ...
Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.

Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems.
The acid facilitates the conversion by the brown, Manganese-containing precipitate of the Iodide ion into elemental Iodine. The Mn(SO 4) 2 formed by the acid converts the iodide ions into iodine, itself being reduced back to manganese(II) ions in an acidic medium. Mn(SO 4) 2 + 2 I − (aq) → Mn 2+ (aq) + I 2 (aq) + 2 SO 2− 4 (aq)
Manganese precipitates in soils in the form of manganese-iron oxide minerals, which promote nutrient and organic matter accumulation due to their high surface area. Manganese is the tenth most abundant metal in the Earth's crust, making up approximately 0.1% of the total composition, or about 0.019 mol kg −1 , which is found mostly in the ...
Many mannans are acetylated and some from marine sources, have sulfate esters side chains. Yeast and some plants such as conjac and salep have a different type of mannans in their cell wall, with a α(1-6) linked backbone and α(1-2) and α(1-3) linked glucose branches, hence "glucomannan". It is water soluble.
It is a small to moderately tall palm that grows in clusters to 5–7 metres (16–23 ft), rarely 9 m (30 ft) tall, with slender stems less than 15 centimetres (5.9 in) diameter. The leaves are palmate (fan-shaped), with segments joined to each other for about half of their length, and are 1–2 m (3.3–6.6 ft) wide, light-green above, and ...
