Question

Write the equations for
i) The action of $S{O}_2$ with chlorine in the presence of charcoal
ii) The action of $S{O}_3$ with concentrated sulphuric acid
iii) The action of ozone with lead sulphide.

Answer 1

The balanced equations are given below.
i) $S{O}_2\left(g\right)+C{l}_2\left(g\right)\to S{O}_{2}C{l}_2\left(l\right)$
ii) $S{O}_3+H_{2}S{O}_4\to H_2{S}_2{O}_7$
iii) $4O_3\left(g\right)+PbS\left(s\right)\to PbS{O}_4\left(s\right)+4O_2\left(g\right)$
