In this work, solubilities of calcium sulfate dihydrate and calcium hydroxide for the ternary systems of CaSO_4 ~2H_2 O-NaOH-H_2O, CaSO_4 ~2H_2 O-KOH-H_2 O, and Ca(OH)_2-NaOH-H_2O were measured by using the classic isothermal dissolution method over the temperature range of 25...
Figs 9.9 and 9.10 can be used to obtain K, PCa and PAlk for the stability index. Similar indices may be used to predict barium sulfate or strontium sulfate or calcium sulfate deposition. If the product of concentration of Ca++ ions and SO4−2ions exceeds the solubility products (KSP) of...

Calculate the solubility (in g/L) of cadmium sulfide in water from the solubility product constant 8×10−27. Solubility: The solubility is the property of the substance. It can be measured by calculating the amount of solute that can be dissolved in the ...
Solubility product constant (Ksp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation.
Solubility Measurement of Calcium Sulfate Dihydrate in NH_4Cl-(NH_4)_2SO_4 Solutions and Thermodynamic Calculation The solubility of gypsum(CaSO_4·2H_2O) in ammonium solutions plays a significant role to prevent gypsum from scaling on the heater and tower in the treatm... P Tian,PG Ning...
The solubility of calcium sulfate dihydrate (DH) and alpha-calcium sulfate hemihydrate in formamide aqueous solutions with 0-13 m formamide at temperatures from 303.15 to 363.15 K was measured by the dissolution equilibrium method. Forma... B Yu,S Miao,Y Zhang,... - 《Journal of Chemical &...
The solubility equilibrium is measured for saturated solution. The solubility equilibrium is specific for a given substance. Alternative name for solubility equilibrium is solubility product constant. The solubility equilibrium is varies depending on the temperature. Chemical tables most often give values fo...
