The process provides for the preparation of MgO from the reaction of magnesium salt and alkali/lime. The crude Mg(OH) 2 is directly calcined and then treated with water to disintegrate the mass spontaneously to yield a slurry and dissolve away the soluble salts. This slurry is much easier to filter and wash than the original Mg(OH) 2 slurry, which helps to speed up the …

Meanwhile, the isolated strain also showed plant growth-promoting traits such as the production of indole-3-acetic acid (IAA), siderophore, ACC deaminase, and phosphate solubilization activity.
In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution.. The extent of the solubility of a substance in a specific solvent is generally measured as the concentration of the solute in a saturated solution, one in which no more solute can ...
Calcium sulphate . Common name – Plaster of Paris. Formula – CaSO 4.1/2H 2 O . By heating gypsum at 393 K. CaSO 4.2H 2 O 393K 🡪 CaSO 4.1/2H 2 O + 3/2H 2 O. It is a hemihydrate of calcium sulphate. On heating, it loses its water of crystallization and forms its anhydrous form which is called 'dead burnt plaster'. Used in treatment of ...
Depending on the type of leaching environment used the uranium will be complexed as either a uranyl sulphate, predominantly UO 2 (SO 4) 3 4-, in acid leach conditions or a uranyl carbonate, predominantly UO 2 (CO 3) 3 4-in a carbonate leach system. This can then be precipitated with an alkali, e.g. as sodium or magnesium diuranate.

Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum, producing a distinct layer called the B horizon.This is a somewhat arbitrary definition as mixtures of sand, silt, clay and humus will support biological and agricultural activity before that time.

Alkali, or Alkaline, soils are clay soils with high pH (greater than 8.5), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 metre depth. Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swell and difficult to clarify/settle.
