Potassium chloride has a high melting point due to its strong ionic bonding between potassium cations and chloride anions. The electrostatic forces holding the ions together require a significant amount of energy to break, leading to the high melting point of potassium chloride.

Why does potassium chloride have a high melting point?
Potassium chloride is an ionic compound. The bond holding the atoms together is known as ionic bond. Strictly speaking it is NOT a discrete molecule of K + Cl- but a crystal lattice consisting of each K+ surrounded by Cl- ions and vice versa. The bonds in this lattice all have to be broken to melt the compound. There is a strong electrostatic force of attraction between the chloride ions and the potassium ions. A large amount of heat energy has to be applied to break the strong bond holding the atoms, resulting in the compound having a high melting point.
What kind of solid is KCl?
KCl, or potassium chloride, is a solid that belongs to the class of ionic compounds. It exists as a crystalline solid at room temperature and has a high melting point.
Does sodium chloride have a high or low boiling point?
Iodine, at p=p0,Boiling point 457.4 K,  184.3 °C(So I don't know if you'd call this high or low? compared with what?)However the difference with melting point of Iodine (386.85 K,  113.7 °C) is remarkably small (< 71oC) and the solid is quite vaporous far below its boiling point (Triple point 386.65K (113.5oC), 12.07 kPa, just below melting point).
Is potassium chloride elemental potassium?
No, potassium chloride is a compound made of potassium and chloride ions. Elemental potassium refers to pure potassium in its uncombined form.
Why copper(ii)chloride has a high melting point than ethane?
Copper(II) chloride has a high melting point compared to ethane because it has ionic bonding, which requires more energy to break compared to the weak van der Waals forces between ethane molecules. In ionic compounds like copper(II) chloride, the positive and negative ions are strongly attracted to each other, resulting in a higher melting point.
Which of the following is true about the melting point of potassium chloride?
The melting point of potassium chloride is relatively high, around 776 degrees Celsius. At this temperature, potassium chloride transitions from a solid to a liquid state.
Melting temperature of potassium chloride?
The melting point of potassium chloride (KCl) is 770 degrees Celsius.

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.
Why does strontium chloride have a high melting point?
Strontium chloride has a high melting point because of the strong attraction between the strontium cations and chloride anions in its crystal lattice. These ionic bonds require significant energy to break, leading to a high melting point.
Does NaCl have high melting point?
No , table salt (sodium chloride) has a melting point of 801°C
Is potassium fluoride volatile?
Yes, potassium fluoride is a solid compound at room temperature and is not considered volatile. It has a high melting point and is stable under normal conditions.
Salt has a high melthing point?
The melting point of sodium chloride is 801 0C.
What chemical bond has a high melting point?
NaCl (sodium chloride)
What is the melting point of sodium cloride?

Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
What kind of solid is KCl?
KCl, or potassium chloride, is a solid that belongs to the class of ionic compounds. It exists as a crystalline solid at room temperature and has a high melting point.
