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.
When molten, the Na+ and Cl- ions are mobile and so can conduct electricity.
The sodium reacts violently with water, producing large amounts of heat. This heat is sufficient to melt the sodium.
Pure sodium chloride doesn't change the color during heating.
Sodium chloride become a liquid at 801 0C.
The dissolution of sodium chloride is considered as a physical process.
no
Sublimation is a physical change.
Crystalline sodium chloride is an insulator.Liquid or melted sodium chloride is a conductor.
Bright yellow
No, sodium chloride does not decompose when heated.
In a flame, sodium chloride produces a bright orange-yellow colour.
sodium is a vomit colour with bits of grass mixed through
The melting point of sodium chloride is 801 0C.
The concentration of sodium chloride increase.
Sodium chloride become a liquid at 801 0C.
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.
After 1 413 0C pure sodium chloride is vaporized without any residue.
well , the colour of potassium chloride is a lilac colour :) hope this helps
Sodium Chloride is neutral. And Phenolphthalein is colourless when neutral.
Sodium Chloride is not a gas solid. It is in crystalline form which when heated, becomes molten. It never evaporates to give Sodium Chloride gas i.e. NaCl.
