Potassium iodide has a higher boiling point because it is ionically bonded while water is polar covalent (with hydrogen bonds). The ionic bonds on KI are stronger than the bonds of water. This means that the molecules are "stuck" to each other stronger than water's molecules. Then it would take more energy (heat) to "unstick" them to change its state of matter, resulting in a higher boiling point.

What is the melting point of KI?
The melting point of potassium iodide (KI) is 681 degrees Celsius (1,258 degrees Fahrenheit).
What is the correct formula for potassium and Iodine?
Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". The formula for the compound formed between potassium and iodine, however, is KI.
How do you prepare iodine solution?
To prepare iodine solution, dissolve iodine crystals in a mixture of water and potassium iodide (KI). The ratio of iodine to KI will determine the concentration of the solution. The solution should be stored in a dark bottle to prevent degradation from light exposure.
Why is KCL soluble in water?
KCl (potassium chloride) is soluble in water because it can undergo ionization in water, breaking into its constituent ions (K+ and Cl-) which become surrounded by water molecules in a process called hydration. This interaction between the ions and water molecules stabilizes the ions in solution, leading to the solubility of KCl in water.
What is the symbol for potassium iodide?
The symbol for potassium iodide is KI.
What has the lowest boiling pt KCl or KI?
The boiling point of potassium iodide is 1 330 0C. The boiling point of potassium chloride is 1 420 0C.
Highest boiling point between NH3 HCl H2 and KI?
KI has the highest boiling point among the given compounds because it has stronger intermolecular forces due to its larger size and increased polarizability compared to NH3, HCl, and H2.
Which compound will have a lower melting point KI or CaI2?
KI will have a lower melting point compared to CaI2. This is because KI is a simple ionic compound with weaker forces holding the ions together, while CaI2 has stronger ionic bonds due to the presence of a divalent calcium ion.
What is the maximum amount of KI that can be dissolved in 50 mL of water at 30 C?
The solubility of KI at 30°C is about 50g/100mL of water. Therefore, in 50mL of water, you can dissolve a maximum of 25g of KI at 30°C.
What is the melting point of KI?
The melting point of potassium iodide (KI) is 681 degrees Celsius (1,258 degrees Fahrenheit).

How do you separate KI and water?
To separate potassium iodide (KI) from water, you can use techniques like evaporation or filtration. Evaporation involves heating the solution to evaporate the water and leave behind the solid KI. Filtration can also be used to physically separate the KI crystals from the water by passing the solution through a filter paper or a sieve.
Is KI soluble or insoluable?
Potassium iodide (KI) is highly soluble in water, meaning it dissolves well in it.
What substance produced in the reaction of chlorine water and KI was confirmed by its reaction with starch?
The substance produced in the reaction of chlorine water and KI is potassium iodide (KI), which reacts with chlorine to form iodine. The confirmation of iodine's presence was done by its reaction with starch, producing a blue-black complex.
Is KI compound insoluble in water?
Potassium iodide (KI) is soluble in water, meaning it can dissolve and form a homogeneous solution when mixed with water.
Is ki aqueous?
No, ki is not aqueous. Aqueous refers to a substance that is dissolved in water. Ki is a term in Japanese culture that represents life energy or spirit in a more abstract sense.
What is the solubility of KI?
KI is highly soluble in water, with a solubility of approximately 31.6 g/100 mL at 25°C.
