Chemical change because physical change is just altering the physical appearance of something, like tearing a paper in half, that is a physical change.
What else can I help you with?
Is dissloving a chemical or physical change?
Dissolving sugar or table salt in water is purely a Physical change
Is dissolving table salt in a bowl of soup be chemical or physical change?
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.
How could you prove to someone that the dissolving of table salt was a physical change not a chemical change?
The chemical formula of sodium chloride is not changed by dissolution.
When table salt dissolves in water is it a physical or chemical property?
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.
When table salt is added to water the ionic compound dissolves. Does this represent a physical change or a chemical change?
Dissolving table salt in water represents a physical change, not a chemical change. The salt molecules remain intact and simply disperse in the water, without any chemical bonds being broken or formed.
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 table sat in a jar of water and the salt being left behind a physical change?
Dissolving in water is a physical change. Evaporation of water also.
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.
Dissolving table salt in water a chemical or physical change?
i think its a phyiscal change cause wen u leave it outside to evaporate u can still get the salt out
Is dissolving sodium chloride in water a physical or chemical charge?
Dissolving sodium chloride (table salt) in water is a physical change. When sodium chloride dissolves, it dissociates into its constituent ions (sodium and chloride) but retains its chemical identity. The process is reversible; the salt can be recovered by evaporating the water, demonstrating that no new substances are formed.
How could you prove that dissolving table salt in water is a physical change or not a chemical change?
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
Is dissolving a solid a physical or chemical change?
it depends on if the solid is also water. if they are both water then its a physical reaction because it just changes the state of matter. if the solid isn't water then its chemical because the two substances then transform into one new substance.
