Sea water `65xx10^(-3) g//"litre"` of bromide ions. If all the bromide ions are converted to produce `Br_(2)`, how much sea water is needed to prepare `1 kg Br_(2)`?

Text Solution

Verified by Experts

`2Br^(-)rarrBr_(2)`
Eq. of `Br^(-) =` Eq.of `Br_(2)`
`(w)/(80)=(10^(3))/(160//2)`
`w_(Br^(-))=10^(3)g`
`:.` Sea water needed `=(10^(3))/(65xx10^(-3))`
`=15.38xx10^(3)"litre"`
