Answer:
Sulphuric acid
H2SO4 is made as a by-product of other operations or directly from elemental
sulphur, spent (contaminated and diluted) H2SO4, and hydrogen sulphide. Elemental sulphur is by far the most widely used raw material.
Hydrochloric acid
HCl is produced in various processes, such as in the reaction between NaCl and
H2SO4, or by direct synthesis from H2 and Cl2. HCl is also a major by-product in
chemical processes when organic compounds are synthesised.
Nitric acid
HNO3 is difficult to manufacture as a pure substance due to its tendency to
decompose. Virtually all HNO3 manufacture is by oxidation of ammonia.
