Question

Insoluble salts can be prepared by:

• A. double decomposition
• B. titration
• C. precipitation
• D. both $\left(A\right)$ and $\left(C\right)$

Answer 1

The correct option is D both $\left(A\right)$ and $\left(C\right)$

Double decomposition generally yields a precipitate.

$NaCl\left(aq\right)+AgN{O}_3\left(aq\right)⟶AgCl\left(s\right)\downarrow +NaN{O}_3\left(aq\right)$

Double decomposition reactions are of two types:

$1.$ Precipitation

$2.$ Neutralization

Precipitation reaction suggests from the name itself that precipitate is formed.
