Problem # 4 Use the silver-copper phase diagram shown below to answer the following questions 900F 961.93 2940 700FB 900 600F8 900° -4 800 800 780° 71.9 (Cu)/ 7.9 700 200F 600 OO0F 500 850F 400 10 20 30 40 50 60 70 80 90 Ag 2 Mass percentage silver Section 4.3 Assume that you have 50 kg of the same liquid solution that you started with in Section 4.2 (that is 30% Ag-70% Cu (by mass) and answer the following questions a. b. c. d. How many kg of Ag will be present in the initial mix? How many kg of Cu will be present in the initial mix? In what phases and in what quantities will copper be present at 900 °C? In what phases and in what quantities will silver be present at 900°C?

Explanation / Answer

Initially there is 99% Ag

99% of 50 kg = 49.5kg

B): initially there is 2% Cu

2% of 50kg= 0.5 kg Cu

C) at 900c we have 41%cu

41% of 50 kg=20.5 kg in solid phase

D): at 900C we have 59% Ag

59% of 50 kg=29.5 kg and in liquid phase
