To maintain a constant potential of the Ag/AgCl electrode an electrolyte solution is needed, which has sufficient chloride ions (Cl-) and which is pH-neutral. Commonly used are KCl solutions, which are 3 molar or saturated. With gel filled electrodes there is sufficient potassium chloride in the gel.

Interestingly, several elements are absorbed as oxyanions, ions composed of the element surrounded by three or four oxygen atoms, giving a net negative charge. ... Iron can be found as either Fe3+ or Fe2+, with a difference in redox state as well as ionic charge.

The electronic configuration of Fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6 and Fe3+ is 1s2 2s2 2p6 3s2 3p6 3d5.

Iron (III) Chloride is an ionic compound, its formula unit is FeCl3 . This indicates that FeCl3 is the smallest repeating unit within the repeating crystal lattice structure of the compound. In general, ionic compounds are classified as ones that are composed of both a metal and a nonmetal.

FeCl3 is an acid salt because Fe(OH)3 is weak base and HCl is a strong acid. pH is less than 7.

The compound is white, but typical samples are often off-white. FeCl2 crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in commerce and the laboratory. There is also a dihydrate. The compound is highly soluble in water, giving pale green solutions.

We could write the chemical formula for this ionic compound as MgClCl, but the convention is to use a numerical subscript when there is more than one ion of a given type—MgCl2. This chemical formula says that there are one magnesium ion and two chloride ions in this formula.

For example, MgCl2 becomes three particles (Mg++ and 2 Cl-) when dissolved in water. Multiply the number of particles produced from dissolving the solution in water by the molarity to find the osmolarity (osmol). For instance, if your have a 1 mol solution of MgCl2: 1 x 3 = 3 osmol.
