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.
Is dissolving of salt physical change or a chemical change?
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.
Is dissolving common salt in water physical or chemical change?
Dissolving is a physical process.
Is dissolving Skittles in salt and water a chemical or physical change?
Dissolving Skittles in salt and water is a physical change. The Skittles are still the same chemical compounds, but they are now dispersed throughout the water-salt solution.
Salt dissovled in water physical or chemical?
Dissolving in water is a physical change.
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.
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 dissolving a chemical reaction?
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.
Is dissolving of salt physical change or a chemical change?
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.
Is salt dissolves in water a physical or a chemical?
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.
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 dissolving in water chemical or physical?
Physical
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 common salt in water physical or chemical change?
Dissolving is a physical process.
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.
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 the solubility of HCl in water a physical phenomenon or a chemical reaction?
Dissolving HCl (or any other dissolvable compound, eg. sugar, salt) in water is physical.
