If the substance does not change, then it can be assumed that there was no physical or chemical reaction. Depending on what you are trying to accomplish, further testing with different substances or conditions may be necessary.
Chemical properties can only be determined by changing a substance.

Colorless is a physical property. Determining change requires you to compare two things.
The acidity or alkalinity of a substance can be determined using a pH indicator. pH indicators change color depending on the pH of a solution, allowing for the determination of whether the substance is acidic, neutral, or basic.

As long as the temperature and pressure remain constant, the density of a substance will not change. Density is determined by the mass of a substance and its volume, and as long as these factors remain constant, the density will remain the same.
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
A substance's chemical composition, which is determined by the types and arrangement of its atoms, always remains the same regardless of physical or chemical changes that may occur.

If the substance is in liquid form, the pH may be determined by litmus paper.
a physical change will only alter the appearance but will NOT change the substance to another substance =)
