Compound Q is a white crystalline solid that dissolves readily in water. If concentrated sulfuric acid is added to a dry sample of Q, steamy white fumes are produced; when these are passed into aqueous silver nitrate solution, a white precipitate is formed. This precipitate dissolves in dilute ammonia solution. What could be the identity of compound Q?
- AAgCl
- BNaBr
- CNaCl
- DPbBr$_2$
