Write the net ionic reaction of : {eq}\rm Na_2CO_3(aq) + 2HNO_3(aq) \to 2NaNO_3 + H_2O(l) + CO_2(g) {/eq}.
Question:
Write the net ionic reaction of : {eq}\rm Na_2CO_3(aq) + 2HNO_3(aq) \to 2NaNO_3 + H_2O(l) + CO_2(g) {/eq}.
Writing Net Ionic Equation:
The net ionic equation is a part of the total ionic equation and represents only the actual chemical change that takes place in a chemical reaction.
The spectator ions that do not participate in the chemical change are eliminated in the net ionic equation.
Answer and Explanation: 1
- The total ionic equation for the given molecular equation is:
{eq}2Na^{+}(aq) + CO_{3}^{2-} (aq) + 2H^{+}(aq) + 2NO_{3}^{-}(aq) \rightarrow 2Na^{+}(aq) + 2NO_{3}^{-}(aq) + H_{2}O(l) + CO_{2}(g) {/eq}
- Thus, {eq}Na^{+} {/eq} and {eq}NO_{3}^{-} {/eq} ions are the spectator ions and the net ionic equation would be:
{eq}2H^{+}(aq) + CO_{3}^{2-}(aq) \rightarrow H_{2}O(l) + CO_{2}(g) {/eq}
