KI is used with silver nitrate to make silver iodide (AgI), an important chemical in film photography. KI is a component in some disinfectants and hair treatment chemicals.
Chemical Properties. Potassium iodide can be oxidized into an I 2 molecule by introducing an oxidizing agent to it. An example of such a reaction is provided below. 2KI + Cl2 → 2 KCl + I2. This compound is used as an iodide source in several organic synthesis reactions.
29 Ιουλ 2024 · This boiling point calculator tells you how to calculate the boiling point of most common substances at an arbitrary pressure, based on the Clausius–Clapeyron relation. Whether you want to analyze water, ethanol, or ammonia, simply provide some reference values, and this calculator will do the work for you.
12 Ιουλ 2023 · According to Table \(\PageIndex{1}\), the molal boiling point elevation constant for water is 0.51°C/m. Thus a 1.00 m aqueous solution of a nonvolatile molecular solute such as glucose or sucrose will have an increase in boiling point of 0.51°C, to give a boiling point of 100.51°C at 1.00 atm.
ΔTb = Tb(solution) −Tb(solvent) = Kb × m (1) (1) Δ T b = T b (s o l u t i o n) − T b (s o l v e n t) = K b × m. where ΔTb Δ T b is the boiling point elevation, Kb K b is the boiling point elevation constant, and m is the molality (mol/kg solvent) of the solute. A solution is prepared when 1.20 g of a compound is dissolved in 20.0 g of ...
The boiling point of KI is 1,330 °C (2,426 °F). This high boiling point is due to the strong ionic bonding between potassium and iodine atoms in the compound. KI is used in high-temperature applications due to its ability to withstand extreme heat without decomposing or losing its effectiveness. Potassium Iodide Melting Point.
