Is mixing salt and silver nitrate a physical or chemical change?

Answer 1

This would be a chemical change because you should be causing some sort of reaction. Physical properties are readily observable, like; color, size, luster, or smell. Chemical properties are only observable during a chemical reaction.

Answer 2

Solid salt and silvernitrate will be a physical change assuming that atmosphere is dry so that salt does not absorb moisture from it and react with silver nitrate. In aquesous solution, there will be a chemical reaction resulting in heavy white precipitate of silver chloride.

Answer 3

Chemical: NaCl(aq) + AgNO3(aq) ===> AgCl(s)+ NaNO3(aq)
