Aqueous solutions of calcium chloride tend to be slightly acidic due to the influence of the chloride ions on the hydrogen ion concentration in water. The slight acidity of calcium chloride solutions is primarily due to the increased ionic strength of the solution, which can influence the activity of hydrogen ions and lower the pH slightly. The ...
i = 2.3 for calcium chloride in water, due to nearly full dissociation of CaCl 2 into Ca 2+ and 2Cl − (often simplified as 3) Non integer i factors result from ion pairs in solution, which lower the effective number of particles in the solution. Equation after including the van 't Hoff factor ΔT b = K b · b solute · i
The first solvation shell of a sodium ion dissolved in water. 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 ...
A dilute (3–6%) aqueous solution in water, historically known as Eau de Labarraque or "Labarraque's water", [17] is widely marketed as a household cleaning product, under the name "liquid bleach" or simply "bleach". More concentrated solutions are used to disinfect drinking water and as bleaching agents
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 heat to precipitate.
Ringer's solution is a solution of several salts dissolved in water for the purpose of creating an isotonic solution relative to the body fluids of an animal. Ringer's solution typically contains sodium chloride , potassium chloride , calcium chloride and sodium bicarbonate , with the last used to buffer the pH .
Calcium peroxide or calcium dioxide is the inorganic compound with the formula CaO 2. It is the peroxide (O 2 2−) salt of Ca 2+. Commercial samples can be yellowish, but the pure compound is white. It is almost insoluble in water. [3]
Calcium hypochlorite is produced on an industrial scale and has good stability. Strontium hypochlorite, Sr(OCl) 2, is not well characterised and its stability has not yet been determined. [citation needed] Upon heating, hypochlorite degrades to a mixture of chloride, oxygen, and chlorates: 2 ClO − → 2 Cl − + O 2 3 ClO − → 2 Cl − ...
