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.
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.
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.
No. The dissolving of salt in water is an exothermic process because it releases energy in the form of heat.
Dissolving table salt in a bowl of soup is a physical change because it doesn't alter the chemical composition of the salt or soup. The salt molecules simply spread out within the soup due to the intermolecular forces between the salt and water molecules.
It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.
No.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
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.
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.
The dissolving of salt in water is a physical change because it does not result in a chemical reaction. The salt molecules are simply breaking apart and becoming dispersed in the water, but there is no change in the chemical composition of the salt.
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.
Dissolving salt into water is a physical change because no chemical reaction takes place, while the state of matter of the salt changes.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
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.
a chemical reaction
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.
A salt is a type of chemical compound, not a reaction.
