A chemical change is when a substance is formed into an entirely new substance, with different properties, as such, a chemical change cannot be reversed. So in answer to your question, salt, in this case the solute (the substance that is being dissolved), is dissolved into water, a solvent (the substance that a solute is dissolved into), so you would think that a chemical change has taken place. But actually, a physical change (when something is changed, but keeps its properties, for example, when you break chalk in two, it is still chalk, only smaller), because if you heat the saltwater, then the water will evaporate, leaving the salt behind, in its original form.

Are glass breaking and sugar dissolving examples of physical changes?
Yes, glass breaking is an example of a physical change because the composition of the glass remains the same even though its appearance has changed. Sugar dissolving is also a physical change because the sugar molecules are simply dispersing in the water without a chemical reaction taking place.
Is dissolving in water physical or chemical?
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
Is dissolving tables in salt water a physical change?
Dissolving tablets is a physical change, as they can be distilled out again.

Is dissolving in water a chemical change?
Dissolving in water is a physical change.
What 4 examples of physical change?
Melting of ice into water. Dissolving sugar in water. Crumpling a piece of paper. Breaking a glass bottle.
Is cofee dissolving in water a physical or chemical change?
It is a physical change.
Is evaporation a physical or chmical change?
a physical because it becomes water again a chemical means it can not change back
Is dissolving powder into water a chemical change?
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
Are glass breaking and sugar dissolving examples of physical changes?
Yes, glass breaking is an example of a physical change because the composition of the glass remains the same even though its appearance has changed. Sugar dissolving is also a physical change because the sugar molecules are simply dispersing in the water without a chemical reaction taking place.
Is an antacid tablet dissolving in a glass of water chemical change?
Well, honey, when that antacid tablet hits the water, it's like a party in a glass! Technically speaking, the tablet dissolving is a chemical change because the composition of the tablet is changing as it reacts with the water. So, yes, it's a chemical change, but don't worry, it's just science doing its thing.
Is dissolving in water physical or chemical?
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
Is dissolving tables in salt water a physical change?

Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
