Question

Write chemical, complete ionic and net ionic equations for the reaction between calcium chloride and sodium carbonate solutions

Answer 1

Write chemical, complete ionic and net ionic equations for the reaction between calcium chloride and sodium carbonate solutions.

Solution.

Write chemical equations for the reaction between calcium chloride $(CaCl_2)$ and sodium carbonate $(Na_2CO_3)$ solutions:

$$CaCl_2(aq) + Na_2CO_3(aq) \rightarrow 2NaCl(aq) + CaCO_3(s) \downarrow;$$

Write complete ionic equations for this reaction:

$$Ca^{2+}(aq) + 2Cl^{1-}(aq) + 2Na^{1+}(aq) + CO_3^{2-}(aq) \rightarrow 2Na^{1+}(aq) + 2Cl^{1-}(aq) + CaCO_3(s) \downarrow;$$

Cancel out unchanged (spectator) ions and write net ionic equations for this reaction:

$$Ca^{2+}(aq) + CO_3^{2-}(aq) \rightarrow CaCO_3(s) \downarrow;$$
