PROPERTIES OF SULPHURIC ACID

PHYSICAL PROPERTIES Sulphuric acid is a dense,oily and hygroscopic liquid. Due to its hygroscopic nature it acts as drying agent. Equal volumes of sulphuric acid and water produces a temperature of 120 degree centigrade. Sulphuric acid forms constant boiling mixture at 98.5%.

Name two gasses which cannot be dried by sulphuric acid Name two gasses which cannot be dried by sulphuric acid. Two reason for adding sulphuric acid in water not vice versa.

CHEMICAL PROPERTIES Dilute sulphuric acid behaves as dibasic acid and gives two type of salt- acidic and normal salt. Give balance chemical equation to support the above statement.

CHEMICAL PROPERTIES Dilute sulphuric acid behaves as an acid and hence shows all the common five types of reactions of an acid. Illustrate the above statement with a suitable example of balanced chemical equations of each type. You may take the help of Text-book if required.

Oxidising nature of sulphuric acid Oxidising behavior of sulphuric acid can be attributed due to its ability to produce nascent oxygen. H O W ? STEP-1 H2SO4  H2O + SO2 + [O] STEP-2 Zn + [O]  ZnO STEP-3 ZnO + H2SO4  ZnSO4 + H2O FINALLY ADDING STEP 1 TO 3 Zn + 2 H2SO4  ZnSO4 + 2 H2O + SO2
