Question

write the balanced net ionic equation for the reaction when hclo₃ and ba(oh)₂ 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

$$2HClO_{3}(aq)+Ba(OH)_{2}(aq) ightarrow Ba(ClO_{3})_{2}(aq)+2H_{2}O(l)$$

Step2: Dissociate strong electrolytes

$HClO_{3}$ is a strong acid and dissociates as $HClO_{3}(aq)
ightarrow H^{+}(aq)+ClO_{3}^{-}(aq)$. $Ba(OH)_{2}$ is a strong base and dissociates as $Ba(OH)_{2}(aq)
ightarrow Ba^{2 +}(aq)+2OH^{-}(aq)$. $Ba(ClO_{3})_{2}$ is a soluble salt and dissociates as $Ba(ClO_{3})_{2}(aq)
ightarrow Ba^{2+}(aq)+2ClO_{3}^{-}(aq)$

Step3: Write the complete ionic equation

$$2H^{+}(aq)+2ClO_{3}^{-}(aq)+Ba^{2+}(aq)+2OH^{-}(aq) ightarrow Ba^{2+}(aq)+2ClO_{3}^{-}(aq)+2H_{2}O(l)$$

Step4: Cancel out spectator ions

Spectator ions are $Ba^{2+}$ and $ClO_{3}^{-}$.

Step5: Write the net - ionic equation

$$H^{+}(aq)+OH^{-}(aq) ightarrow H_{2}O(l)$$

Answer:

$$H^{+}(aq)+OH^{-}(aq) ightarrow H_{2}O(l)$$
