The volume of water needed to dissolve 1g of `BaSO_4 (K_(sp) =1.1 xx 10^(-10) ) at 25^(@) C ` is `{ M. W of BaSO_4 is 233}`

A

820 L

B

430 L

C

205L

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
` KsP = S^(2) = 1.1 xx 10 ^(-10) , S ~~ 10^(-5) "mol" // lit`
` 1 gm =(1)/(233)` moles
` therefore ` Volume of water ` = (1//233)/( 10 ^(-5)) = 430 L `
