To `500 cm^(3)` of water, `3 xx 10^(-3) kg` of acetic acid is added. If `23%` of axcetic acid is dissociated wha will be the depression in freezing point? `K_(f)` and density of water are `1.86 K kg^(-1) mol^(-1)` and `0.997 g cm^(-3)` respectively.

Text Solution

Verified by Experts

The correct Answer is:
`0.229`
`DeltaT_(f) = iK_(f)m`
`=(1.23) xx 1.86 xx (3//60)/(500 xx 0.997//1000)`
`= 0.23 K`
