Is salt water considered a physical or chemical change?
Solubilization of salt in water is a physical change.
Is it a physical change chemical change when salt dissolves in water?
Physical
Is the dissolving salt in water a chemical or physical change?
The dissolving of salt in water is considered a physical change, not a chemical change. This is because no new substances are being formed during the process; the salt molecules are simply breaking apart and dispersing throughout the water.
Is solubility of salt in water a chemical or physical change?
Solubilization of salt in water is a physical change.
Are the salt crystals produced when a glass of saltwater is left on a window sill for several days a chemical or physical change?
The formation of salt crystals from saltwater on a window sill is a physical change. In this process, the water evaporates, leaving behind the salt crystals. The composition of the salt remains the same, so it is considered a physical change.
Why would dissolving salt in water be considered a physical change?
This is a physical change. This is a an interesting example - it is considered to be physical because the salt can be recovered through evaporation. However the salt in solution is separated into ions which are solvated by water molecules- this could be argued as a chemical change.- as there are albeit weak interactions between the water and the ions. Some salts dissolve and hydrolysis occurs, a "genuine" chemical reaction with water. An example is sodium acetate, (a salt of a weak acid), this dissolves to give a basic solution- this would be a chemical change. This is reversible - you can evaporate the water and get the salt back.

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.
Is mixing salt and water chemical?
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Is mixting salt and water a physical change?
Physical change...
Dissolving salt into water is it physical or chemical change?
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
Is possolving table salt in a glass of water a physical change of a chemical change?
It is a physical change because the chemical composition of the salt and water does not change.
