Question

Sulphuric acid is diprotic acid and hydrochloric
acid is monoprotic acid. Explain this statement
with the help of suitable examples.​

Answer 1

Answer:

hydrochloric acid

The acid equilibrium problems discussed so far have focused on a family of compounds known as monoprotic acids. Each of these acids has a single H+ ion, or proton, it can donate when it acts as a Brnsted acid. Hydrochloric acid (HCl), acetic acid (CH3CO2H or HOAc), nitric acid (HNO3), and benzoic acid (C6H5CO2H) are all monoprotic acids.

Our techniques for working diprotic acid or diprotic base equilibrium problems can be applied to triprotic acids and bases as well. To illustrate this, let's calculate the H3O+, H3PO4, H2PO4-, HPO42-, and PO43- concentrations at equilibrium in a 0.10 M H3PO4 solution, for which Ka1 = 7.1 x 10-3, Ka2 = 6.3 x 10-8, and Ka3 = 4.2 x 10-13.
