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.
The dose is 0.5 g-1.0 g in 100 mL, with the accompany of iodine (0.5 g-1.0 g in 100 mL). KI is also used as a fluorescence quenching agent in biomedical research because of collisional quenching by its iodide ion.
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.
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.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.
20 Ιαν 2021 · We can use G B D (as in Gmajor), within key C minor. That B note is the leading note, just one semitone under the tonic, here, C. That gives a sonic pull towards the C, and is the main reason why G major sounds so good in key C minor.
