Out of NaCl and `BaCl_(2)` aqueous solutions, which shows more depression in freezing point and Why ?

Text Solution

Verified by Experts

For NaCl
`NaCl (aq) to Na^(+) (aq) + Cl^(-1) (aq) , i = 2 `
For `BaCl_(2)`
`BaCl_(2) (aq) to Ba^(2+) (aq) + 2 Cl^(-)(aq) , i = 3`
Now ` Delta T_(f) = i xx K_(f) xx m `
For same molal concentration, more i, more depression in freezing point. Thus `BaCl_(2)` (aq) . solution will show more depression in freezing point
