when two solutions are mixed and a new color is observed is this color change an indication that a chemical reaction has occurred? Explain why?

  • chemistry -

    Some things you will notice if a chemical reaction has occurred is
    1. heat is evolved.
    2. a precipitate is formed.
    3. a color change occurs.
    4. light is emitted.
    5. a gas is evolved (bubbles in an aqueous phase).
    If any of these things appear you know a different compound(s) has formed.
