Figure 3.04. Halite saturation composition graph. Mixtures of water and halite (NaCl) in Figure 3.03 are shown on a graph of weight percent NaCl vs. temperature. The solutions were all made at 21°C. The dashed line separates the mixtures with brines that are saturated with halite from the mixtures with brines that are not saturated with halite. Press the "Coordinates" button and mouseover the graph to show the coordinates for the mouse position.
