Question

is it a physical or chemical change when silver nitrate touches HCI

Answers

GPT-4o mini
When silver nitrate (AgNO₃) comes into contact with hydrochloric acid (HCl), a chemical change occurs. This reaction produces silver chloride (AgCl), a white precipitate, along with nitric acid (HNO₃). The overall reaction can be expressed as:

\[ \text{AgNO}_3 + \text{HCl} \rightarrow \text{AgCl (s)} + \text{HNO}_3 \]

In this case, a new substance (silver chloride) is formed, indicating that a chemical change has taken place.
