Which of the following statements are correct ?

A

One mole of `Cl_(2)` means 8 equivalents of chlorine when `Cl_(2) rarr Cl^(-) + ClO_(4)^(-)`

B

One mole of `Cl_(2) `means 6 equivalents of chlorine when `Cl_(2) rarr Cl^(-) + ClO_(4)^(-)`

C

When one mole of `As_(2)S_(3)`is oxidised to `As_(2) O_(5)+ SO_(2)` then it mean 22 equivalent of `As_(2)S_(3)` are oxidised

D

The equivalent weight of `As_(2)S_(3)` is always = mol. wt. `//`22.
