Three samples labelled A,B, and C possess identical melting points: 99 degrees. When a 75/25 mixture of A and B is prepared, it’s melting point is 90-95 degrees. The melting point of a 50/50 mixture of A and C is 79-91 degrees. The melting point of a 25/75 mixture of B and C is 97-98 degrees. What information does this tell you about the identity of the 3 compounds? What would you expect an an approximate melting range for a 75/25 mixture of B and C?
