Calcium chloride reacts with sodium hydroxide to form solid calcium hydroxide, Ca (OH) 2. The balanced net ionic equation is

Group of answer choices

Ca+2 (aq) + 2OH - (aq) + 2 Na + (aq) + 2 Cl - (aq) → Ca (OH) 2 (s).

Ca+2 (aq) + 2OH - (aq) + Na + (aq) + Cl - (aq) → Ca (OH) 2 (s).

Ca+2 (aq) + 2OH - (aq) → Ca (OH) 2 (s).

CaCl2 (aq) + 2NaOH (aq) → CaOH (s) + NaCl (aq).

CaCl2 (aq) + 2NaOH (aq) → Ca (OH) 2 (s) + 2NaCl (aq).

Ca²⁺ + 2 OH⁻ → Ca (OH) ₂ (s)

Explanation:

In chemistry, the net ionic equation is a way to write a chemical reaction whereas you write only the ions that are involved in the reaction.

When calcium chloride, CaCl₂ reacts with sodium hydroxide, NaOH to produce Ca (OH) ₂ the only ions involved in the reaction are Ca²⁺ and OH⁻, thus, the balanced net ionic equation is:

Ca²⁺ + 2 OH⁻ → Ca (OH) ₂ (s)

Cl⁻ and Na⁺ are not involved in the reaction and you don't have to write them.
