Question

Make a project on comparative study of the three mineral acids - HCl, HNO3, H2SO4. also include Introduction and Bibliography.​

Answer 1

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.
