Is the addition of heat to solid sodium chloride until it melts a chemical reaction?
Chemical reactions happen on a molecular level Physical reactions are concerned with a change in state or energy level, so melting is considered a physical reaction since there is no molecular change just a change in state.
Is heating sodium chloride a chemical change?
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.
What has the higher melting point sodium chloride or aluminum oxide?
Aluminum oxide has a higher melting point than sodium chloride. Aluminum oxide has a melting point of around 2072°C, while sodium chloride has a melting point of 801°C.
What has been effect of heating sodium chloride?
Heating sodium chloride causes it to undergo a phase change from a solid to a liquid, called melting. Above its melting point of 801°C, sodium chloride will further decompose or evaporate into gaseous sodium and chlorine atoms.
Is heating sodium chloride going to result in a chemical change?
Some water that has bonded with the salt will be removes but otherwise salt is remarkably stable. Eventually (when it gets hot enough) you will ionize it into Cl and Na ions.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
if sodium chloride dissolves in water what is it a chemical or physical change?
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
What is the melting of sodium chloride?
The melting point of sodium chloride is 801 0C.
What is the melting characteristic of sodium chloride?
The melting point of sodium chloride is 801 0C.
What it sodium chloride melting point?
The melting point of sodium chloride is 801 0C.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Which is more effective for melting ice: calcium chloride or sodium chloride?
Calcium chloride is more effective for melting ice than sodium chloride.
Is heating sodium chloride a chemical change?
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.

Why is it sodium chloride have the highest melting temperature?
Why is it sodium chloride have the highest melting temperature
The melting point of the salt sodium chloride (NaCl) is .?
The melting point of sodium chloride ie 801 oC.
Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
