no it isn't. My 6th grade teacher told me that and i still don't really understand it.
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
You can demonstrate that dissolving is a physical change by showing that the chemical composition of the substance remains the same before and after dissolving. This can be done by evaporating the solvent and obtaining the original substance in its solid form. Chemical changes involve a change in the chemical composition of the substances involved, leading to the formation of new substances, which is not the case in dissolving.
Solubility is a physical change, as it involves the dissolving of a solute in a solvent without changing the chemical composition of the substances.

Dissolving is a physical change.
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
