KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.

Why is melting point of sodium fluoride higher than that of sidium iodide?

The higher melting point of sodium fluoride compared to sodium iodide is due to stronger forces of attraction between the ions in the crystal lattice of the fluoride compound. Fluoride ions are smaller and have a higher charge density compared to iodide ions, leading to stronger electrostatic forces between the ions in sodium fluoride, resulting in a higher melting point.

What is the melting point of KI?

The melting point of potassium iodide (KI) is 681 degrees Celsius (1,258 degrees Fahrenheit).


How potassium iodide have a high melting point?

Potassium iodide has a high melting point because it consists of strong ionic bonds between potassium and iodine atoms. These bonds require a significant amount of energy to break, resulting in a high melting point for the compound.

Would fluorine water react with potassium iodide?

Yes, fluorine water (HF) would react with potassium iodide (KI) to form potassium fluoride (KF) and hydrogen iodide (HI). This reaction would typically release iodine gas as a product.

What are the symbols for the ions that form when potassium iodide react to form the ionic compound potassium iodide?

The symbol for the potassium ion is K+ and the symbol for the iodide ion is I-. When potassium iodide (KI) forms an ionic compound, the potassium ion (K+) and the iodide ion (I-) combine in a 1:1 ratio to create KI.
