The question depends on what you start with.
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.
Oxide can not change to chloride, so the actual answer is no. However- if you put sodium oxide together with hydrochloric acid it will end up as sodium chloride and water (and a lot of noise, probably).
no 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.
In water solution, sodium chloride crystals dissociate into sodium cations and chloride anions.
The boiling point of sodium chloride is 1 413 0C.
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
When sodium chloride and silver nitrate react, they form silver chloride precipitation and sodium nitrate in solution. This is a chemical change as new substances are formed with different properties from the original reactants.
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
no
This is a chemical reaction, 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.
