Acids

SULPHURIC ACID – H2SO4
Sulphuric Acid (H2SO4) is a highly corrosive strong mineral acid. It is a pungent-ethereal, colourless to slightly yellow viscous liquid which is soluble in water at all concentrations. The historical name of this acid is oil of vitriol. The acid is and shows different properties depending upon its concentration. Its corrosiveness on other materials, like metals, living tissues or even stones, can be mainly ascribed to its strong acidic nature and, if concentrated, strong dehydrating and oxidizing properties. It has widely varied uses and plays some part in the production of nearly all manufactured goods.

Applications

  • Production of Fertilisers., e.g. superphosphate of lime and Ammonium Sulphate
  • Manufacture of Chemicals e.g. in the making Hydrochloric Acid, Nitric Acid, Sulphate Salts, Synthetic Detergents, Dyes & Pigments, Explosives, Drugs.
  • Petroleum refining; used to remove impurities out of gasoline and other refinery Products.
  • Processing metals e.g. in pickling (cleaning & before plating) metals with Tin or Zinc.
  • Acts as Electrolyte in lead-acid storage battery commonly used in Motor Vehicles (often known as battery acid)


ACETIC ACID – CH3 COOH
Acetic Acid(CH3COOH) also known as Ethanoic Acid, is an organic acid which gives vinegar its sour taste and pungent smell. Pure, water-free acetic acid is a colourless liquid that absorbs water from the environment, and freezes at 16.7 °C (62 °F) to a colourless crystalline solid. It is one of the simplest of carboxylic acids.

Applications

  • Important chemical reagent and industrial chemical, used in the production of polyethylene terephthalate Soft drink bottles
  • Cellulose acetate, used on photographic films; a
  • Polyvinyl acetate, used in wood glue, as well as in synthetic fibres and fabrics
  • In households, diluted acetic acid is used as a descaling agent.
  • In the food industry, acetic acid is used under the food additive code E260 as an acidity regulator


HYDROCHLORIC ACID – HCL
Hydrochloric Acid (HCL) is formed by the reaction of Chlorine and Gaseous Hydrogen, both obtained from the electrolysis of brine. It is a clear, colourless, highly pungent solution of hydrogen chlorine water. It is a highly corrosive, strong mineral acid with many industrial uses.

Applications

  • Metal Pickling
  • Latex Coagulation
  • Dyestuffs
  • Leather Treatment
  • Petroleum Refining
  • Galvanising and Water Treatment


NITRIC ACID – HNO3
Nitric Acid (HNO3), also known as aqua fortis and spirit of nitre. It is a highly corrosive and toxic strong acid that can cause severe burns. Colourless when pure, older samples tend to acquire a yellow cast due to the accumulation of oxides of nitrogen. If the solution contains more than 86% nitric acid, it is referred to as fuming nitric acid, which is categorised as white fuming nitric acid and red fuming nitric acid, depending on the amount of nitrogen dioxide present.

Applications

  • Manufacture of Explosives (TNT, Gun Cotton, Ammonal, Nitroglycerene
  • Purification of Precious Metals (Silver, Gold & Platinum)
  • Etching of Metals
  • Nitrates of Calcium-Silver-Ammonia
  • Synthetic Paints
  • Manufacture of Sulphuric Acid by Lead Chamber Process
  • Dyes, Perfumes, Drugs & Fertilisers
  • Laboratory Reagents


PHOSPHORIC ACID – H3PO4
Phosphoric acid (H3PO4), also known as orthophosphoric acid or phosphoric(V) acid, is a mineral (inorganic) acid. Orthophosphoric acid molecules combine with themselves to form a variety of compounds, which are referred to as phosphoric acids, in a general way. The term 'phosphoric acid'may also refer to a chemical or reagent consisting of phosphoric acids, usually orthophosphoric acid.

Applications

  • Pre-metal treatment Chemical
  • Sugar Refining
  • Anodizing
  • Stabilizing Agent (H2O2)
  • Waste Water Treatment
  • Manufacture of Soaps & Detergents
  • Tea Leaf Processing
