Jeg forstår ikke opgaven, er der nogen, der vil oversætte?
Consider an aqueous 1.00 mol kg-1 solution of Na3PO4, a compound with useful detergent properties. Calculate the boiling point of the solution assuming that:
(a) it does not ionise at all in solution
(b) the van't Hoff factor for Na3PO4 reflects 100 % dissociation into its ions.
The 1.00 mol kg-1 solution boils at 100.83 oC at 1.0 x 105 Pa.
(c) Calculate the van't Hoff factor for the solute in this solution.
Forresten, hvad Periodic acid for noget?
