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

A physical change because only interparticle forces are broken and the solution can be separated through evaporation, a physical process.

B

A chemical change because only intraparticle forces are broken and energy is released by the solution, a chemical change.

C

Both chemical and physical changes due to the breaking of the ionic bonds, resulting in the interaction between the ions and the water molecules.

D

This type of change cannot be classified as either chemical or physical due to the complexity of the process on a molecular level.
