Equivalent weight can be found by -
Equivalent weight=Molecular weight/n
Here, n= number of electrons exchanged per mole
2 S subscript 2 O subscript 3 superscript negative 2 end superscript space space space space space space rightwards arrow space space space space S subscript 4 O subscript 6 superscript negative 2 end superscript
2 x minus 6 equals negative 2 space space space space space space space space space 4 x minus 12 equals negative 2
2 x equals negative 2 plus 6 space space space space space space space space space space 4 x equals 10
2 x equals 4 space space space space space space space space space space space space space space space space space space space space x equals 5 over 2
x equals 2
