Equimolar aqueous solutions of NaCI and BACI_(2) are prepared. If the freezing point of NaCI is -2^(@)C, the freezing point of BaCI_(2) solution is expected to be:

Answer»

`-2^(@)C`
`-3^(@)C`
`-1.5^(@)C`
`-1.66^(@)C`

Solution :`DeltaT_(f)("COLLIGATIVE property")` in linked with number of PARTICLES or IONS in solution
`NaCItoNa_((aq))^(+)+CI_((aq))^(-)`
` BaCI_(2)toBa_((aq))^(2+)+2CI_((aq))^(-)`
`"If "alph a"for " NaCI is -2^(@)C`
`"Then " ALPHA "for" BaCI_(2) "is EXPECTED tobe" =-3^(@)C.`
