Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. The ions are held together by an ionic, or weak salt bond. Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you ad...
This reaction forms calcium hydroxide that dissolves in water as a soda, and hydrogen gas. Other important calcium reaction mechanisms are erosion reactions. These usually occur when carbon dioxide is present. Under normal conditions calcium carbonate is water insoluble. When carbon dioxide is present ...

After cooling and in each tube, 2 ml of aqueous NaHCO3 0.2 M solution were added (to destroy the excess of BF3) and then 0.1 ml HCl 6 M (to ensure that the pH is acidic before extraction). The reaction medium was extracted with 2 ml methylene chloride (in the tube)...
(1) ascertain the major components and structure of GT-NZVI prepared using green tea; (2) confirm the transport ability of GT-NZVI in simulated aquifer; (3) determine the removal effect of Cr(VI) in water and the stability of immobilized Cr in simulated aquifers through in-situ reaction ...
Elementary sodium reacts strongly with water, according to the following reaction mechanism: 2Na(s) + 2H2O → 2NaOH(aq) + H2(g) A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction. Sodium metal is...
What are the molecular, total ionic and net ionic equations of the reaction between aqueous solutions of calcium chloride and sodium carbonate? Phenoxide ion (C6H5O-) is a weak base, with Kb = 7.70 x 10-5. What is the pKa of phenol, C6H5OH, ...
A revised, updated summary of equilibrium constants and reaction enthalpies for aqueous ion association reactions and mineral solubilities has been compiled from the literature for common equilibria occurring in natural waters at 0-100°C and 1 bar pressure. The species have been limited to those con...
