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.
The volume of the mixture prepared by taking 1.158 mol and 0.842 mol of water and ethanol, respectively, was measured as 68.16 cm3 at 25 ° C.Since the partial molar volume of water in the mixture is 16.98 cm3 / mol, find the partial molar volume of ethanol.Since the densities at 25ᴼC for pure water and ethanol are given as 0,9970 g / cm3 and 0,7852 g / cm3, respectively, find the volume change during the preparation of the mixture and interpret the result. (MSu: 18 g / mol; Methanol = 46 g / mol)
A student was instructed to determine the molecular weight of an unknown white powder. He remembered that one way to do this is by exploiting the colligative properties of solution. After a simple conductivity test, he found that an aqueous solution of the sample is not conductive. He dissolved 22.87 grams of the unknown sample in 0.500 kg of water.
