The standard Gibbs free energy of formation (Gf °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 ...
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca (OH) 2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed with water. Annually, approximately 125 million tons of calcium hydroxide are produced worldwide. [8]
Standard electrode potential (data page) The data below tabulates standard electrode potentials (E °), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent ...
The pozzolanic activity is a measure for the degree of reaction over time or the reaction rate between a pozzolan and Ca 2+ or calcium hydroxide (Ca (OH) 2) in the presence of water. The rate of the pozzolanic reaction is dependent on the intrinsic characteristics of the pozzolan such as the specific surface area, the chemical composition and ...
Calcium phosphide (CP) is the inorganic compound with the formula Ca 3 P 2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca 2+ and P 3−. Other, more exotic calcium phosphides have the formula CaP / Ca 2 P 2, CaP 3, and Ca 5 P 8. Ca 3 P 2 has the appearance of red-brown crystalline powder or ...
Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 42– anion involves the removal of two protons from phosphoric acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.
Chart. The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require ...
