For `0.1M` solution ,the colligative property will follow the order

Options

A. `NaCl gt Na_(2)SO_(4)gt Na_(3)PO_(4)`
B. `NaCl gt Na_(2)SO_(4)~~Na_(3)PO_(4)`
C. `NaCl lt Na_(2)SO_(4) lt Na_(3)PO_(4)`
D. `NaCl lt Na_(2)SO_(4)=Na_(3)PO_(4)`

Answer

C

Explanation

Colligative property in decreasing order
`Na_(3)PO_(4)gtNa_(2)SO_(4)gtNaCl`
`Na_(3)PO_(4)rarr3Na^(+)+PO_(4)^(3-)=4`
`Na_(2)SO_(4)rarr2Na^(+)+SO_(4)^(2-)=3`
`NaClrarrNa^(+)+Cl^(-)=2`
