I think there's a problem with this question. It's saying all the options are incorrect. The answer should be silver chloride.
@Myschool the answer should be AgCl because.
Double decomposition is typically used to prepare insoluble salts by reacting two soluble salts
The correct answer is D. Silver chloride.
Why?
Double decomposition (double displacement) reactions usually:
Involve two soluble salts reacting
Produce an insoluble salt (a precipitate)
Key Example:
AgNO₃ (aq) + NaCl (aq) → AgCl (s) + NaNO₃ (aq)
Silver chloride (AgCl) is insoluble, so it forms a precipitate
This is a classic double decomposition reaction
Why others are wrong:
Sodium trioxocarbonate (IV) → usually made by other methods (e.g., Solvay process)
Barium trioxonitrate (V) → soluble, not formed as a precipitate
Lead (II) trioxonitrate (V) → also soluble
The answer is Silver chloride all other salts are soluble except for AgCl which means it can be prepared by double decomposition
