Question

Information and Reactions of Sulphuric acid.

Answer 1

General preparation of H2SO4

\[S + 0_2 \rightarrow S0_2 \]

Answer 2

Now oxidise S02

\[S0_2 + O_2 \rightarrow SO_3\]

Answer 3

Now,
make Oleum

\[SO+3 + H_2SO_4 \rightarrow H_2S_2O_7\]

Answer 4

Ad water to Oleum

\[H_2S_2O_7 + H_2O \rightarrow 2H_2SO_4\]

Answer 5

The reactions stated above are called Contact process

Answer 6

Reactions to show H2SO4 is acidic in nature.

Answer 7

\[Zn + H_2SO_4 \rightarrow ZnSO_4 + H_2\]

\[Na_2O + H_2SO_4 \rightarrow Na_2SO_4 + 2H_2O\]

\[Na_2CO_3 + H_2SO_4 \rightarrow Na_2SO_4 + CO_2 + H_2O\]

\[KHCO_3 + H_2SO_4 \rightarrow K_2SO_4 +2H_2O + CO_2\]

\[2NaHSO_3 + H_2SO_4 \rightarrow Na_2SO_4 + 2H_2O + SO_2 \]

\[FeS + H_2SO_4 \rightarrow FeSO_4 + H_2S\]
