H 2 SO 4 saturated with SO 3 is called oleum or sulphan. H 2 SO 4+ SO 3 longrightarrow H 2 S 2 O 7

Q. ‘Sulphan’ is

a mixture of $S O_{3}$ and $H_{2} S O_{5}$

100% conc. $H_{2} S O_{4}$

a mixture of gypsum and conc. $H_{2} S O_{4}$

100% oleum (a mixture of 100% $S O_{3}$ in 100% $H_{2} S O_{4}$ )

$H_{2} S O_{4}$ saturated with $S O_{3}$ is called oleum or sulphan.
$H_{2} S O_{4} + S O_{3} ⟶ H_{2} S_{2} O_{7}$

Q. ‘Sulphan’ is

a mixture of SO3​ and H2​SO5​

100% conc. H2​SO4​

a mixture of gypsum and conc. H2​SO4​

100% oleum (a mixture of 100% SO3​ in 100% H2​SO4​)

H2​SO4​ saturated with SO3​ is called oleum or sulphan. H2​SO4​+SO3​⟶H2​S2​O7​

a mixture of $S O_{3}$ and $H_{2} S O_{5}$

100% conc. $H_{2} S O_{4}$

a mixture of gypsum and conc. $H_{2} S O_{4}$

100% oleum (a mixture of 100% $S O_{3}$ in 100% $H_{2} S O_{4}$ )

$H_{2} S O_{4}$ saturated with $S O_{3}$ is called oleum or sulphan.
$H_{2} S O_{4} + S O_{3} ⟶ H_{2} S_{2} O_{7}$
