No, this is not a redox reaction (or a chemical reaction at all) because no species gain/lose electrons in this process.
It is a solution, where a solid (solute) is placed between the molecules of a liquid (solvent).
this is a chemical change cause you can't return it back to solid salt
Boiling, Chopping Crushing, Cutting, Freezing, Grinding, Melting Molding, Pounding, Smashing.
The sugar is not chemically changed / oxidized. Gently evaporate the water, and you get the sugar back.
salt water
Common table salt when added to water is an example of a solute. For example, salt crystals (the solute) are the part of salt water (a solution) which has changed its state when added to water (the solvent).
no
Dissolving is not the same thing as melting. When you dissolve salt in water, for example, neither the salt nor the water melts. In the example of salt in water, salt is the solute and water is the solvent. The salt (which is the solute) is what dissolves (but does not melt).
Dissolving salt in fresh water.
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 in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
Salt water is obtained by dissolving sodium chloride in water.
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.
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.
Salt dissolves better in warm water.Also if the salt is in water it will automatically dissolve if the water is hot or cold.So in that case heat does not effect the dissolving of salt.
No. It is a physical change. All you have to do to separate the two is to evaporate the water. There is no chemical change.
When you first mix the salt into the solution the salt will dissolve into the water. As you keep on pouring more salt into the water eventually the salt will stop dissolving and once the salt stops dissolving the solution is then saturated.
