Question
Which relations are not correct for an aqueous dilute solution of K3PO4 if its degree of dissociation is α ?
Options
A.
B.
C.
D.Mw of K3PO4 = Mwobs × (1 + 3α)
Solution
For electrolyte
(Mw1 = 18 for H2O)
Also, pobs = C × R × T (1 + 3α)
∴
ᐃTf obs = Kf × molality × (1 + 3α)
i = (1 + 3α) =
Therefore, molecular weight of K3PO4 = Mobs × (1 + 3α)
