List of top Chemistry Questions on Depression of freezing point asked in CBSE Class XII

How does sprinkling of salt help in clearing snow-covered roads in hilly areas? Name the colligative property involved.

60 g of glucose is dissolved in 250 g of water. Calculate the freezing point of this solution.
(molar mass of glucose = $180~g~mol^{-1}$, $K_f$ for water = $1.86~K~kg~mol^{-1}$)

An antifreeze solution is prepared by dissolving 31 g of ethylene glycol (Molar mass = 62 g mol$^{-1}$) in 600 g of water. Calculate the freezing point of the solution. (K$_f$ for water = 1.86 K kg mol$^{-1}$)

An antifreeze solution is prepared by dissolving \(31g\) of ethylene glycol \((M=62g\,mol^{-1})\) in \(600g\) of water. Calculate the freezing point of the solution. \[ K_f\text{ for water}=1.86K\,kg\,mol^{-1} \]

An antifreeze solution is prepared by dissolving 31 g of ethylene glycol (Molar mass = 62 g $\mathrm{mol^{-1}}$) in 600 g of water. Calculate the freezing point of the solution. ($\mathrm{K_f}$ for water = 1·86 K kg $\mathrm{mol^{-1}}$)
