Question

making predictions about reactions
choose the correct products for the double replacement reaction below. click here to access the solubility rules to determine which product, if any, forms a solid precipitate in the reaction.
$\text{agno}_3 + \text{kcl}
ightarrow ?$
$circ$ $\text{k} + \text{o}_2 + \text{ncl}$
$circ$ $\text{kno}_3 + \text{agcl}$
$circ$ $\text{agk} + \text{clno}_3$
$circ$ $\text{k}_2\text{no}_3 + \text{agcl}_2$
done

Explanation:

Step1: Identify double replacement pairs

In double replacement, cations swap: $\text{Ag}^+$ pairs with $\text{Cl}^-$, $\text{K}^+$ pairs with $\text{NO}_3^-$.

Step2: Write neutral products

$\text{KNO}_3$ (potassium nitrate, neutral) and $\text{AgCl}$ (silver chloride, neutral).

Step3: Verify solubility

$\text{KNO}_3$ is soluble; $\text{AgCl}$ is a solid precipitate (insoluble per rules).

Answer:

$\text{KNO}_3 + \text{AgCl}$ (the second option)
