Theoretically, metal salts are substances that are formed when hydrogen in an acid gets replaced by a metal. This is carried out in practice by reacting metal oxides with the acid. Every existing acid gives its particular set of Salt, for example, Sulfates are formed through the reaction of Sulphuric acid and metals, Chlorides are formed by carrying out a reaction between Hydrochloric acid and metals, Nitrates are a result of the reaction between Nitric acid and metals. These salts are popularly used for electroplating, production of dyes and pigments, for carrying out galvanization, in pesticides for protecting plants from pest, etc. Some examples of routinely used metal salts are Ammonium Dichlorate, Sodium Bicarbonate, Magnesium Sulfate, Sodium chloride is also known as the table salt, etc.
Nickel is a silvery-white shiny metal that slightly appears golden. It is a chemical element exhibiting hardness and ductility. Nickel salts like nickel chloride are used in Electroplating and other scientific processes.
Copper is a pink-orange chemical element showing malleability, ductility and low heat resistant and high electric conductivity. Its salts have agricultural importance as fungicides and industrial uses.
Zinc is a bluish-silver chemical element that shows slight brittleness at room temperature. Zinc salts are used as corrosion preventive elements due to zinc being highly non-corrosive.
Tin is a soft chemical element that is seemingly silverish with a faint yellowish hue. Tin salts like tin chloride are widely used as reducing agents and during tin plating as a constituent of the electrolytic baths.
Lead is a heavy chemical element with a low melting point showing malleability and softness. Its salts are used in the textile industry as dyes and in paints as a drier.
Metal and Metal Salts
Metal salts are the combination of metal cations and non-metal anions. Metal salt is formed when a hydrogen atom is replaced by a metal ion. Metal salts are formed when a metal replaces the hydrogen of an acid. From a reaction of a metal with hydrochloric acid (HCl) we get chlorides, and from a reaction of a metal, or metallic compound, with sulfuric acid (H2SO4) we get sulfates, with phosphoric acid (H3PO4) yields phosphates, etc. Example: Copper Sulphate, Nickel sulphate, Nickel Chloride, Stannous sulphate, Stannous oxide, Stannous Chloride.
Metal salts and metal salt solutions are used in the electroplating industry and Metal finishing Industries.
It is used for plating iron and brass, equipment, and manufacturing certain alloy that retain a high silvery polish, such as silver.
Nickel forms compounds with all common anions, including sulphate, carbonate, hydroxide, chloride. Nickel Sulphate is produced in large quantities by dissolving nickel metal or oxides in sulfuric acid, forming both a hexa- and heptahydrates useful for electroplating.
Copper and Copper Alloys
Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys.
Copper Sulphate and Copper Chloride is produced in large quantities by dissolving metal in mineral acids both are useful for electroplating, Agriculture, Dyeing and Inks.
Numerous copper alloys have been formulated, many with important uses.
Brass is an alloy of copper and Zinc.
The metal’s distinctive natural green patina has long been coveted by architects and designers.
Zinc is most commonly used as an anti-corrosion agent, and galvanization is the most familiar form. Zinc is more reactive than iron or steel and thus will attract almost all local oxidation until it completely corrodes away. The zinc is applied electrochemically or as molten zinc by hot dip galvanizing or spraying.
In latest technology zinc flakes deposit is most popular as it requires thin deposit and corrosion resistance is 3-4 higher than other popular zinc coatings.
Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like Lead, is soft enough to be cut without much force.
Tin bonds readily to Iron and is used for coating lead, zinc and steel to prevent corrosion.
Tin Coated steel containers are widely and this forms a large part of the market for metallic tin and this forms a large part of the market for metallic tin.
Tin in combination with other elements forms a wide variety of useful alloys. Tin Sulphate and Tin Chloride is produced in large quantities by dissolving metal in mineral acids both are useful for electroplating, cosmetics and pharmaceutical.
