Figure P2.33 shows a portion of the H,O-NaCl phase diagram. 10 Liquid (brine) Salt Ice + -10 F liquid (brine) liquid (brine) -20 Ice + salt -30 NaCI 10 20 30 H2O 100 90 80 70 FIGURE P2.33 Composition, weight % a. Using the diagram, briefly explain how spreading salt on ice causes the ice to melt. Show numerical examples in your discussion. b. At a salt composition of 10%, what is the temperature at which ice will start melting? c. What is the eutectic temperature of the ice and salt combination? Temperature, °C
