2.32 Calculate the depression in the freezing point of water when of is added to of water.
Firstly we will find the Vant's Hoff factor the dissociation of given compound.
So we can write,
Putting values of Ka and C in the last result, we get :
At equilibrium i = 1 - a + a + a = 1 + a = 1.0655
Now we need to find the moles of the given compound CH3CH2CHClCOOH.
So, moles =
Thus, molality of the solution :
Now we will use :
