Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
How can we describe a single-phase material?
Pure naphthalene melts at 80 °C. Pure I-naphthol melts at 123°C. All mixtures of these two components show a single peak when heated and a 50 mol% mixture shows a single broad peak around 100 °C. What type of phase diagram does this suggest? Draw a hypothetical example of this type of phase diagram.
substance melts sharply at 135°C. Is it a pure compound? Explain.
Describe the phase changes that take place when a liquid mixture of 4.0 mol B2H6 (melting point 131 K) and 1.0 mol CH3OCH3 (melting point 135 K) is cooled from 140 K to 90 K. These substances form a compound (CH3)2OB2H6 that melts congruently at 133 K. The system exhibits one eutectic at x(B2H6) = 0.25 and 123 K and another at x(B2H6) = 0.90 and 104 K.
Two samples have exacted the 1 point same melting points, so the samples are: If the mixture has the same melting point of the two samples then the compounds identical to each other (Same compounds). The same intermolecular forces. The same structure Different to each other's.
