Figure 5.8 shows the phase diagram for the ternary system NH₄Cl/ (NH₄)₂SO₄/H₂O at 25 °C. Identify the number of phases present for mixtures of compositions (i) (0.2, 0.4, 0.4), (ii) (0.4, 0.4, 0.2), (iii) (0.2, 0.1, 0.7), (iv) (0.4, 0.16, 0.44). The numbers are mole fractions of the three components in the order (NH₄Cl,(NH₄)₂SO₄,H₂O).
