Calcium bicarbonate, also called calcium hydrogencarbonate, has the chemical formula Ca (HCO 3) 2. The term does not refer to a known solid compound; it exists only in aqueous solution containing calcium (Ca 2+ ), bicarbonate ( HCO−. 3) ions, together with dissolved carbon dioxide (CO 2 ). The relative concentrations of these carbon ...
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. Approximately 125M tons/y are produced worldwide.
Ca(NO 2) 2 + Ca(OH) 2 + H 2 O → Ca(NO 2) 2 •Ca(OH) 2 •H 2 O. 2. Liberation of calcium nitrite Ca(NO 2) 2 •Ca(OH) 2 •H 2 O--H 2 O → Ca(NO 2) 2 (aq) + Ca(OH) 2 + H 2 O Uses. Calcium nitrite has a great variety of uses. It can be use as antifreeze due to its high solubility, either in solution or powder. It can promote the hydration of ...

Calcium nitrate is a very common coagulant in latex production, especially in dipping processes. Dissolved calcium nitrate is a part of the dipping bath solution. The warm former is dipped into the coagulation liquid and a thin film of the dipping liquid remains on the former. When now dipping the former into the latex the calcium nitrate will ...
The Hardest Logic Puzzle Ever is a logic puzzle so called by American philosopher and logician George Boolos and published in The Harvard Review of Philosophy in 1996. [1] [2] Boolos' article includes multiple ways of solving the problem. A translation in Italian was published earlier in the newspaper La Repubblica, under the title L ...
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq). The word aqueous (which comes from aqua) means pertaining ...
