Answer to Question #119116 in Physical Chemistry for Durgamadhab

Question

bi-cd eutectic mixture has 40% of Cd by mass.

then what would happen if a molten mixture of Bi and Cd containing 15% of Cd is gradually closed to the eutectic temperature of the system?

Answer 1

Area B represents Bi and Cd in solid state.

Are A represents solid Cd and liquid mixture.

So if you reach the E-point temperature from above solidification of Cd first happen and then Bi becomes solid at T lower than E-temperature.
