which would make water impure? adding chemicals adding ice
Answer
Answer:
adding chemicals
Explanation:
Step1: Analyze adding ice
Ice is solid - state water. Adding ice to water just changes the physical state of water and does not introduce foreign substances, so it does not make water impure.
Step2: Analyze adding chemicals
Chemicals are substances other than water. Adding them to water will introduce foreign substances, thus making the water impure.
