Question

$AgN{O}_{3\left(aq\right)}+NaC{l}_{\left(aq\right)}\to AgC{l}_{\left(s\right)}+NaN{O}_{3\left(aq\right)}$.
Above reaction is a:

• A. Precipitation reaction
• B. Double displacement reaction
• C. Combination reaction
• D. (a) and (b) both

Answer 1

The correct option is D (a) and (b) both

Often, a precipitate forms in a double displacement reaction. In this reaction-
$AgN{O}_3+NaCl\to AgCl+NaN{O}_3$
both $AgN{O}_3$ and $NaCl$ exchange their ions to form new compounds, $AgCl$ (ppt) and $NaN{O}_3$. Hence, it shows both double displacement and precipitation.
