When silver nitrate (AgNO₃) is mixed with hydrochloric acid (HCl), a chemical change occurs. This is because the two reactants undergo a chemical reaction to form silver chloride (AgCl), which is a solid precipitate, and nitric acid (HNO₃). The formation of a precipitate is a key indicator of a chemical change, as new substances with different properties are formed. Therefore, the mixing of silver nitrate with HCl leads to a chemical change.
We had videos to watch about physical and chemical changes. They are mixing together silver nitrate along with HCI. Is that a physical or chemical change?
