Potassium Iodide | KI or IK | CID 4875 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. It is used mainly in the form of a saturated solution, 100 g potassium iodide to 100 ml water. That equates to around 50 mg/drop.
Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points.
25 Οκτ 2010 · The key thing to consider here is that boiling points reflect the strength of forces between molecules. The more they stick together, the more energy it will take to blast them into the atmosphere as gases. There are 3 important trends to consider.
1 Οκτ 2010 · The intermolecular forces increase with increasing polarization of bonds. The strength of intermolecular forces (and therefore impact on boiling points) is ionic > hydrogen bonding > dipole dipole > dispersion. Boiling point increases with molecular weight, and with surface area.
23 Ιαν 2023 · The melting points of crystalline solids cannot be categorized in as simple a fashion as boiling points. The distance between molecules in a crystal lattice is small and regular, with intermolecular forces serving to constrain the motion of the molecules more severely than in the liquid state.
In this post, we will talk about the melting and boiling points of organic compounds and their correlation with intermolecular forces such as dipole-dipole, London dispersion (also known as Van der Waals) interactions, and hydrogen bonding.
