Dilute HCl does not react with nitrates but can react with silver nitrate to form a white precipitate of silver chloride.
HCl + AgNO3 → AgCl + HNO3
- Hydrogen chloride (HCl) is a colourless gas that forms white fumes of hydrochloric acid when brought into contact with atmospheric humidity.
- The hydrogen and the chlorine atom are connected by a covalent single bond, which is highly polar since the chlorine atom is much more electronegative than the hydrogen atom.
- Hydrogen chloride gas can cause irritation of the eyes, skin, and respiratory tract.
