Simple chemistry question: what is the difference between colligative and chemical interactions of molecules?
When you say chemical interactions of molecules, I am going to assume you mean intermolecular forces, and the truth is that Colligative Properties and Intermolecular Forces are actually related. In essence, the Intermolecular forces (chemical interactions, IMF for short) between two things give way to their Colligative Properties. If there is a substance, such as pure water, that has a freezing point of 0 degrees celsius (32 degrees fahrenheit), and you add to it a substance that has a lower freezing point than that, such as Salt (sodium chloride, NaCl), than the substance (water mixed with salt) takes on some of the properties of each substance. This works in a few different ways. Colligative Properties: These are comparing the properties of a pure solvent (eg. Pure water) to those of a solution. Vapor Pressure of solution is Lower Boiling Point of solution is Higher Freezing Point of solution is Lower Also, Osmosis occurs when a solvent and solution are separated by a semi-permeable
