WitrynaThe effect of Raoult's Law is that the saturated vapour pressure of a solution is going to be lower than that of the pure solvent at any particular temperature. That has important effects on the phase diagram of the solvent. The next diagram shows the phase diagram for pure water in the region around its normal melting and boiling points. WitrynaNote that in the single-phase region (above the equilibrium curve), the temperature increases from right to left. On the CO 2–H 2O mixture phase diagram, also note the areas where a liquid water-rich phase exists. At higher water concentration (Figure 1f), the two areas with water-rich phases merge. The new area is denoted by (j) in the …
