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.
Calcium chloride is a highly soluble calcium salt. Hexahydrate calcium chloride (CaCl 2 ·6H 2 O) has solubility in water of 811 g/L at 25 °C. [1] Calcium chloride when taken orally completely dissociates into calcium ions (Ca 2+) in the gastrointestinal tract, resulting in readily bioavailable calcium. The high concentration of calcium ions ...
A piper diagram and two ternary diagrams on the composition of intrusive volcanic rocks; see QAPF diagram. A Piper diagram is a graphic procedure proposed by Arthur M. Piper in 1944 for presenting water chemistry data to help in understanding the sources of the dissolved constituent salts in water.
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
The situation for calcium is more complicated. Neutron diffraction data gave a solvation number for calcium chloride, CaCl 2, which is strongly dependent on concentration: 10.0 ± 0.6 at 1 mol·dm −3, decreasing to 6.4 ± 0.3 at 2.8 mol·dm −3. The enthalpy of solvation decreases with increasing ionic radius.
The star shape comprises eight kite-shaped polygons, the area of each of which is proportional to the concentration of an ion in milliequivalents per litre. The anions carbonate, bicarbonate, chloride and sulphate are on the left, while the cations potassium, sodium, calcium and magnesium are on the right.
