Microscale Experiment on Decreases in Volume When Forming Binary Liquid Mixtures: Four Alkanol Aqueous Solutions

摘要: The volume of a liquid mixture is not equal to the sum volumes its components. In this study, microscale experiments and theoretical calculations from experimental data such as excess molar or densities are applied mixing alkanol (methanol, ethanol, 1-propanol, 2-propanol) water, observed calculated alkanol-water mixtures (aqueous solutions) obtained. Both in good agreement, alkanols water drastically reduced ca 1/25 using comparison with traditional ones. treatment also easy for high school university students. Therefore, it has been demonstrated that our methods useful informative teaching materials science first grade chemistry classes
