As sodium chloride is heated, the vibrations of the individual sodium chloride molecules increase, forcing adjacent sodium chloride molecules to move away until they have enough room to vibrate. Once the temperature increases to 801 °C (1,474 °F), the molecules are so far apart that they can't hold together anymore. So, they fall apart and act as a liquid. Viola, molten sodium chloride.

What does sodium chloride become when heated?
When heated, sodium chloride (table salt) remains as solid salt. When heated to very high temperatures, around 801°C (1474°F), it will melt into a liquid form. Only when it reaches the extreme temperature of 1465°C (2669°F) does it decompose into its constituent elements, sodium and chlorine.
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.
Will sodium chloride change Methyl orange yellow?
no
Which will not form water and carbon dioxide when it burns?
Sodium chloride (table salt) will not form water and carbon dioxide when it burns. When sodium chloride is heated, it may decompose into sodium and chlorine, but it does not produce water and carbon dioxide as products.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
What colour of flame does sodium chloride produce when heated?
Sodium chloride does not produce a flame when heated. It simply melts into a liquid state and eventually vaporizes.
What color does sodium chloride change to when heated in water?
sodium is a vomit colour with bits of grass mixed through
What colour would sodium chloride produce in heat?
In a flame, sodium chloride produces a bright orange-yellow colour.
Why is it that sodium chloride does not dissolve when heated?
The melting point of sodium chloride is 801 0C.
WHAT HAPPENS TO THE SODIUM AND CHLORIDE IF THE SALT WATER IS HEATED?
The concentration of sodium chloride increase.
What is the residue when sodium chloride water solution was heated to dryness?
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
Does dodium chloride decompose when heated?
No, sodium chloride does not decompose when heated.
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 residue is left after sodium chloride is heated?
After 1 413 0C pure sodium chloride is vaporized without any residue.
What is the gas evolved when ammonium chloride and sodium nitrate is heated together?
The gas evolved when ammonium chloride and sodium nitrate are heated together is nitrogen gas (N2). This reaction results in the decomposition of ammonium chloride and sodium nitrate to form nitrogen gas, water vapor, and sodium chloride.
What is the color change between aqueous bromine and sodium chloride?
There will be no colour change between the two, as chlorine is more electronegative than bromine and will maintain its negative charge, meaning that the bromine will not react and the orange colour persists.
What is sodium chlorate heated?
The chemical equation is:2 NaClO3 = 2 NaCl + 3 O2
