18 ml o 1.0 M Br_(2) solution undergoes complete disproportionation in basic medium to Br_(ϴ) and Br_(3)^(ϴ) . Then the resulting solution requires 45 ml of As^(+3) solutioni to reduce BrO_(3)^(ϴ) to Br^(ϴ).As^(+3) is oxidised toAs^(+5) which statements are correct?

Answer»

`E_(w)(Br_(2))=M/10`
`E_(w)(Br_(2))=(5M)/3`
Molarity of `As^(+3)=0.4M`
Molarity of `As^(+3)=0.2M`
