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
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
Although the exact temperature can be hard to control, the weight ratio of salt to ice influences the temperature: −10 °C can be achieved with a 1:2.5 mass ratio of calcium chloride hemihydrate to ice. −20 °C can be achieved with a 1:3 mass ratio of sodium chloride to ice. [citation needed]
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 ...
Brine (or briny water) is a high-concentration solution of salt (typically sodium chloride or calcium chloride) in water.In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).

Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
