16 Μαΐ 2017 · Aqueous calcium and chloride ions play determinant roles in various biological or environmental phenomena, and understanding their thermodynamics is of primary importance. 1 Among the microscopic quantities that remain to be characterized, the formation of associated Ca 2+-Cl − pairs, despite its apparent simplicity, is not well understood ...
20 Μαΐ 2013 · We prepared three calcium chloride–expanded graphite (CaCl2 : EG/4 : 1) composite samples (labelled B1, B2, and B3) with varying water content (20–45% by weight), and also used a conventional...
1 Ιαν 2023 · A new thermodynamic model has been developed in the framework of the combined HKF-Pitzer equations in order to describe solution properties and phase diagrams of aqueous chloride systems bearing calcium, up to elevated temperatures.
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
Since HCl is a strong acid, K a is immeasurably large and K b ≈ 0 (chloride ions don’t undergo appreciable hydrolysis). Thus, dissolving ammonium chloride in water yields a solution of weak acid cations (NH 4 + NH 4 +) and inert anions (Cl −), resulting in an acidic solution.
Calcium chloride is a very common chemical in energy efficiency thermal engineering applications.
1 Φεβ 2018 · Calcium chloride (CaCl2) from deicing salts can react chemically with calcium hydroxide [Ca (OH)2] from hydrated cement paste to form an expansive product, calcium oxychloride, that can...
