The final acid obtained during the manufacture of $$H_{2}SO_{4}$$, by contact process is:

A$$H_{2}SO_{4}$$ (conc.)
B$$H_{2}SO_{4}$$ (dil)
C$$HCl$$
D$$H_{2}S_{2}O_{7}$$
Correct Answer

Solution

During contact process $$H_{2}S_{2}O_{7}$$ is formed which is further diluted to get sulphuric acid of desired concentration.
$$H_{2}SO_{4} + SO_{3}\rightarrow H_{2}S_{2}O_{7}$$
$$H_{2}S_{2}O_{7} + H_2O\rightarrow 2H_{2}SO_{4}$$
