Final answer:
The net ionic equation for the reaction between copper(II) chloride and barium hydroxide is Cu²⁺ (aq) + 2OH⁻ (aq) → Cu(OH)₂ (s).
Step-by-step explanation:
The net ionic equation for the reaction between copper(II) chloride and barium hydroxide can be written as follows:
Cu²⁺ (aq) + 2OH⁻ (aq) → Cu(OH)₂ (s)
In this equation, the copper(II) ion (Cu²⁺) from the copper(II) chloride reacts with the hydroxide ion (OH⁻) from the barium hydroxide to form solid copper(II) hydroxide (Cu(OH)₂). The 2+ charge on the copper ion is balanced by the 2- charge on the hydroxide ion, resulting in a neutral compound.
