Cobalt(II) acetate is the cobalt(II) salt of acetic acid. It may also be found as the tetrahydrate.

It may be formed by the reaction between cobalt oxide or hydroxide and acetic acid:

    CoO + 2 HC2H3O2 → Co(C2H3O2)2 + H2O

Cobalt(II) acetate may be reacted with salenH2 to give salcomine, an oxygen-transport compound:[1]

    Co(OAc) + salenH2 → Co(salen) + 2 HOAc

Cobalt(II) acetate is harmful if swallowed or inhaled. It may cause an allergic skin reaction. Chronic exposure may affect heart, thyroid, lungs, and kidneys.

Cadmium acetate is the chemical compound with the formula Cd(CH₃CO₂)₂. This colourless solid is classified coordination polymer, featuring acetate ligands interconnecting cadmium centers. The compound exists in anhydrous form and as a dihydrate. It forms by treating cadmium oxide with acetic acid:

CdO + 2 CH₃COOH → Cd(CH₃COO)₂ + H₂O

Silver acetate is a photosensitive, white crystalline substance. It is commonly used as a pesticide. It also produces a repulsive taste when combined with cigarette smoke, that's why t is used in chewing gum and lozenges to aid the cessation of smoking.

The main application of magnesium chloride is production of magnesium metal. This is done by the precipitation process for which the formula is given in the common reactions section. Magnesium chloride is also used for a variety of other applications like the manufacture of textiles, paper, fireproofing agents, cements and refrigeration brine, and dust and erosion control. Also, presence of magnesium chloride in water decreases its freezing point making magnesium chloride a perfect anti-icer.
