The dissolution of 80.0 g sodium hydroxide in a 2.00 L volumetric flask brought to volume with deionized water at room temperature can be classified by which of the following?
A physical change because only interparticle forces are broken and the solution can be separated through evaporation, a physical process.
A chemical change because only intraparticle forces are broken and energy is released by the solution, a chemical change.
Both chemical and physical changes due to the breaking of the ionic bonds, resulting in the interaction between the ions and the water molecules.
This type of change cannot be classified as either chemical or physical due to the complexity of the process on a molecular level.
