Copper (II) chloride is used as a catalyst for organic and inorganic reactions, mordant for dyeing and printing of textiles, pigment for glass and ceramics, wood preservative, disinfectant, insecticide, fungicide, and herbicide, and as a catalyst in the production of chlorine from hydrogen chloride. Other important applications are in copper plating of aluminum, preparation of copper standard solutions, testing for molybdenum, in tinting-baths for iron and tin, in pigments for ceramics and glasses, as a fixer and desensitizer reagent in photography, in mercury extraction from ores, in laundry-marking and invisible inks, and in the manufacture of various copper salts.

Copper(II) tetrafluoroborate is commonly used as a copper electroplating material and in the production of printed circuits. It is also deployed as a component of fluxing, as a catalyst and as an active filler in resin bonded abrasives. In organic chemistry laboratories, it is used to facilitate synthetic reactions such as the Diels-Alder reaction.

Lead fluoborate is a crystalline powder that is normally disolved in a water solution. It is used as an electroplating solution for metal objects, as a curing agent for epoxy resins and a catalyst in the production of linear polyesters.

Nickel chloride is used for nickel plating cast zinc, as an agent in electrolytic refining of nickel, as a chemical intermediate for nickel catalysts and complex nickel salts, and as an absorber of ammonia gas in industrial gas masks, among other uses.

Nickel nitrate is used in the preparation of nickel-impregnated catalysts. It also is used to make nickel plates in nickel-cadmium batteries. Other applications are in ceramics to produce brown colors and in preparing nickel oxide.

Silver nitrate is a natural compound with antiseptic activity. It can be used as a cauterizing or sclerosing agent and can help create a scab to help stop bleeding from a minor skin wound. In its solid form, silver nitrate is commonly used as a precursor to other silver-containing compounds. It is used in making photographic films and in laboratory setting as a staining agent in protein visualization in PAGE gels and in scanning electron microscopy.

As a solution, stannous chloride containing a little hydrochloric acid is used for the tin-plating of steel, in order to make tin cans. An electric potential is applied, and tin metal is formed at the cathode via electrolysis. Other uses include the deployment as a mordant in textile dyeing to impart brighter colours with some dyes such as cochineal.

Stannous (tin) fluoroborate is most commonly used as an electrolyte in electroplating for tin and is also used with lead fluoroborate for lead-tin plating. It is also used for plating bath tinned copper, tin and tin alloy. Furthermore, it acts as a catalyst for various organic reactions. It is also used as a petrochemical additive.
