Question

The equivalent weights of $S$ in $S{Cl}_2$ and $S_2{Cl}_2$ are in the ratio:

• A. $1:2$
• B. $2:1$
• C. $1:1$
• D. $1:4$

Answer 1

The correct option is A $1:2$

$i)$ Equivalent weight of sulphur in $SC{l}_2=\frac{\text{Atomic mass of}S}{\text{valency of}S}=\frac{32}{2}=16$

$ii)$ Equivalent weight of sulphur in $S_{2}C{l}_2=\frac{\text{Atomic mass of}S}{\text{valency of}S}=\frac{32}{1}=32$

Ratio of equivalent weight of $S$ in $SC{l}_2$ and $S_{2}C{l}_2$ is $16:32=1:2$.
