Question

write the balanced net ionic equation for the reaction when alcl₃ and naoh are mixed in aqueous solution. if no reaction occurs, simply write only nr. be sure to include the proper phases for all species within the reaction.

Explanation:

Step1: Write the molecular equation

$AlCl_3(aq)+3NaOH(aq)
ightarrow Al(OH)_3(s) + 3NaCl(aq)$

Step2: Write the complete ionic equation

$Al^{3 + }(aq)+3Cl^{-}(aq)+3Na^{+}(aq)+3OH^{-}(aq)
ightarrow Al(OH)_3(s)+3Na^{+}(aq)+3Cl^{-}(aq)$

Step3: Cancel out the spectator ions

Spectator ions are $Na^{+}$ and $Cl^{-}$. After canceling them, we get the net - ionic equation.
$Al^{3+}(aq)+3OH^{-}(aq)
ightarrow Al(OH)_3(s)$

Answer:

$Al^{3+}(aq)+3OH^{-}(aq)
ightarrow Al(OH)_3(s)$
