(C) Sulphurous acid is an inorganic compound with the chemical formula $H_{2}SO_{3}$.It is formed when sulphur dioxide $(SO_{2})$ is dissolved in water $(H_{2}O)$.The reaction is: $SO_{2} + H_{2}O \rightarrow H_{2}SO_{3}$.In contrast,$H_{2}SO_{4}$ is sulphuric acid,$H_{2}S_{2}O_{7}$ is oleum,and $H_{2}SO_{2}$ is sulphoxylic acid.
