Question

Two liquids were added to each other that results in a different color liquid. Jackson said, "We observed a chemical change, because a new color was formed." Carsyn said, "It may have been a physical change, if it was only mixing paint colors." Who is correct and why?

A. Carsyn is correct, because only unexpected color changes are chemical changes. You would need other evidence to show a chemical change occurred.

B) Carsyn is correct, because color change is always a result of a physical change.
C) Jackson is correct, because color change always indicates a chemical change.
D) Jackson is correct, because color change means an new substance was formed.

Answer 1

The answer is A, for anyone who came here looking for the correct answer like I was... Your welcome lol

Answer 2

The correct answer is option A. Carsyn is correct, because only unexpected color changes are chemical changes. You would need other evidence to show a chemical change occurred.

The color changes can be a case of chemical changes, but mixing of two colored solution (in this case, paint) can come up with a new color by physical mixing only.

It is observed any unexpected color changes, which means the color change, which cannot be obtained by mixing two existing color denotes the chemical reaction. So, Jackson's statement may or may not be true. So, to determine if it is a chemical change or a physical change some further research should be done.
