The change that occured when the chemistry teacher mixed two clear substances and a solid forms is a chemical change.

What are chemical changes?

A chemical change is a process in which reactants are changed into products by the breaking or creation of chemical bonds.

On the other hand, a physical change is a change affecting the form of a chemical substance, but not its chemical composition.

The characteristics of a chemical change are as follows;

  • Temperature changes
  • Light given off
  • Unexpected color changes
  • Bubbles are formed
  • Different smell or taste
  • A solid (precipitate) forms if two clear liquids are mixed

Therefore, the formation of a precipitate when the teacher mixed two clear substances is an example of chemical change.
