Yes. A salt is an ionic compound and so dissolving (or hydrolyzing) it is a chemical reaction. An example with sodium chloride (table salt): NaCl (solid) -> Na+ + Cl- The charges on the products indicate that they are aqueous (in solution). Since the reactant breaks apart into it's products, this is a dissociation reaction.

Explain why dissolving is a physical change?
All physical changes are reversible because the molecules do not undergo change in any chemical reaction even in in the change in the state of matter. NaCl is a salt compound and each molecules gets easily dissolved in water and the salt recovered by evaporation of water.
Is salt dissolved in water a chemical or physical change?
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
Is dissolving sugar in water a chemical property?
No dissolving of sugar is not a chemical property because no reaction takes place.
Is dissolving table salt in a bowl of soup be chemical or physical change?
Dissolving salt in soup is a physical change.
Is salt dissolving in water an example of an endothermic reaction yes or no?
no
Is salt dissolving a chemical or physical reaction?
No.
Is dissolving salt in water a physical or chemical change?
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
What is chemical change when dissolving?
1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.
Is dissolving salt in water chemical or physical change?
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
Is salt dissolves in water a physical or a chemical?

Why is salt in water a physical change?
Dissolving salt into water is a physical change because no chemical reaction takes place, while the state of matter of the salt changes.
Is salt dissolved in water a chemical or physical change?
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
What is sugar dissolving and example of?
a chemical reaction
Is salt dissolving in water chemical or physical react ion?
This is an example of a physical reaction, as the salt can be separated from the water once more by evaporation - they can be returned to their original states.
Is dissolving sugar in water a chemical property?
No dissolving of sugar is not a chemical property because no reaction takes place.
