Question 35

While studying chemical and physical changes, students added salt to a glass of water. They stirred the salt until it dissolved and could no longer be seen. "That's a chemical change," Sarah stated. Do you agree? Explain.

Accepted Answer

No, it is a physical change. It is salt and water and you can get the salt back by boiling off the water.

Answer

Yes, it is a chemical change because something new is formed.

Answer

Yes, it is a chemical change because there was a change in the appearance of one of the components, the salt.
