Solubility of gypsum vs ph
WebWhile sparingly soluble, gypsum is one of the more soluble calcium compounds. It is over 100 times more soluble in water than calcium carbonate or lime (at neutral pH of 7), but much less soluble than calcium nitrate or calcium chloride, which are used in fertigation programs and as foliar fertilisers. Gypsum contains sulfur as sulfate, the ...

Consider the following formula of Henry's law: p = kh c. where: p is the partial pressure of the gas above the liquid, kh is Henry's law constant, and. c is the concentrate of the gas in the liquid.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall.

The scaling occurred following a sharp drop in the reject-brine pH when an acidic effluent (pH < 2) was introduced. Batch experiments revealed that the antiscalant is effective in postponing nucleation and …

Gypsum should be surface-applied and not incorporated. If soil pH is less than 5, the application might be harmful to plants present at the time of the application. In this situation, it would be recommended to use liming to correct soil pH, and then reevaluate for gypsum application as needed.
