Write the peroxy acids and polythionic acids of sulphur.

Peroxy acids of sulphur are:

Amino acid having sulphur is

The acid anhydride of sulphuric acid is

Why is peroxy acid weaker than carboxylic acid ?

Write a balanced equation for the reaction of - sulphur and hot consentrated nitric acid.

Some bacteria obtain their energy by oxidising sulphur, producing sulphuric acid as a by-product. In the laboratory, or in industry, the first step in the conversion of sulphur to sulphuric acid is to produce sulphur dioxide. The sulphur dioxide is converted to sulphur trioxide, which reacts with water to give sulphuric acid. Write the equation for the conversion of sulphur dioxide to sulphur trioxide. Why does this reaction supply energy?

Write the difference in the electrolysis of dilute sulphuric acid and 50% sulphuric acid at Pt electrodes.

In the Contact process state why sulphur trioxide vapours are absorbed in concentrated sulphuric acid and not in water to obtain sulphuric acid .

Give balanced equations for the following conversions : Nitric acid to sulphuric acid

Select the monoprotic, diprotic and triprotic acids from the following: (i) Hydrochloric acid (ii) Sulphuric acid (iii) Phosphoric acid (iv) Acetic acid
