WebThe ionic strength of a solution is a function of the concentration of all ions present in a solution: (5) I = 1 2 ∑ i z i 2 c i. Here, c i and z i are the molar concentration and the charge of ion i. The sum is taken over all ions in the solution. Due to the square of z i, multivalent ions contribute particularly strongly to the ionic strength. Calcium chloride can be used to precipitate fluoride ions from water as insoluble CaF 2. Calcium chloride is also an ingredient used in ceramic slipware. It suspends clay particles so that they float within the solution, making it easier to use in a variety of slipcasting techniques. Meer weergeven Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising Calcium … Meer weergeven Calcium chloride dissolves in water, producing chloride and the aquo complex [Ca(H2O)6] .
