Sodium Chloride (Salt) has a lattice structure and since it is a solid, there is limited movement of the atoms within the structure. The structure of water is very different, the molecules of water are linked through hydrogen bonds and inter-molecular bonds within the individual water molecules . The molecules in water can also move more freely relative to those in salt.
This means that more energy is required to break the bonds within the lattice structure of salt since there are a greater number of bonds connecting the atoms. The bonds between water molecules are broken with less energy, hence water boils at a lower temperature than salt decomposes (it does not 'melt').
Sodium chloride has a high melting point of around 800°C due to its strong ionic bonds between sodium and chloride ions. These bonds require a significant amount of energy to break, resulting in a high melting point.
It's due to the nature of the compunds. Water is a covalent molecule, which generally have low melting points due to weak intermolecular forces, whereas salt is an ionic lattice, which usually have high melting points because energy is needed to overcome the electromagnetic force binding the ions together.
Salt doesn't melt in ice. Salt lowers the freezing point of water. Which causes the ice to melt.

Sodium chloride melting point reduced by adding calcium chloride?
By adding calcium chloride to sodium chloride, the melting point of the mixture is reduced because calcium chloride is a salt that disrupts the sodium chloride lattice structure. This disruption makes it easier for the sodium chloride to transition from a solid to a liquid state, lowering its melting point.
What temperature does sodium hydride decompose at?
Sodium hydride decomposes at temperatures above 400°C, releasing hydrogen gas in the process.
What state would copper be at 800 degrees?
Copper would be in liquid form at 800 degrees Celsius. Copper has a melting point of 1084 degrees Celsius, so at 800 degrees, it would have already melted but not yet boiled into a gas.
Why calcium chloride and calcium flouride are added to the electrolyte in the down cell during extraction of sodium metal?
Calcium chloride and calcium fluoride are added to the electrolyte in the down cell during the extraction of sodium metal to improve the conductivity of the electrolyte. This helps in the smooth flow of electric current during the electrolysis process, ensuring efficient extraction of sodium metal. Additionally, these compounds help to increase the melting point of the electrolyte, which is important for maintaining the high temperatures required for the extraction process.
What metal melts at 800 degrees?
Lead has a melting point of around 621 degrees Fahrenheit, which is close to 800 degrees. Lead is a soft, dense, and malleable metal frequently used in construction, batteries, and bullets.
The melting point of the salt sodium chloride is?
The melting point of sodium chloride (NaCl) is 801 degrees Celsius or 1474 degrees Fahrenheit.
Sodium chloride melting point reduced by adding calcium chloride?
By adding calcium chloride to sodium chloride, the melting point of the mixture is reduced because calcium chloride is a salt that disrupts the sodium chloride lattice structure. This disruption makes it easier for the sodium chloride to transition from a solid to a liquid state, lowering its melting point.
Can salt melt in heat?
No. The salt does not melt in water, but it dissolves in water. The melting point of common salt (sodium chloride along with other metal salts as impurities) requires very high temperatures (exceeding 800 Degrees C) to melt. The process of melting and dissolving in a solvent are two distinct and totally different ball games, if you will.
Is a solid with a melting point of 800 degrees Celsius ionic or molecular?
A solid with a high melting point of 800 degrees Celsius is more likely to be ionic rather than molecular. Ionic compounds typically have higher melting points compared to molecular compounds because of the strong electrostatic forces between the charged ions in the crystal lattice.
How does Table salt changes to a liquid at 808 degrees?
Table salt does not change into a liquid at 808 degrees. Table salt, which is sodium chloride, has a melting point of 1474 degrees Fahrenheit (801 degrees Celsius). This means that it needs to be heated to a higher temperature to turn into a liquid.
What liquid metal has a 800 celsius melting point?
Cerium (58) has a melting point of 799 deg C.
What does 800 milliliters of salt mean?
1. A volume of powdered sodium chloride.2. A volume of water solution of sodium chloride with a non-specified concentration in this case..
What is bohrium's melting point?
Bohrium's melting point is not well-defined due to its synthetic nature and short half-life. Its estimated melting point is around 600-800 degrees Celsius.
What is the melting point of a Pyrex test tube?
A glass hasn't a true melting point. The softening point of Pyrex glass is between 800 °C and 850 °C.
What happens when sodium chloride and water is heated?
The water will boil if its temperature is brought high enough. The significant difference between boiling water and boiling water with sodium chloride in it is that the NaCl water will boil sooner. Adding salt to water will lower its boiling point as well as its freezing point. This is also why the road is salted in sub zero weather: to hinder the road from becoming icy.
What is the melting point of seashells?
The seashell is fomed from calcium carbonate; CaCO3 is thermally decomposed by heating.
What temperature does sodium hydride decompose at?
Sodium hydride decomposes at temperatures above 400°C, releasing hydrogen gas in the process.
