Answer:

no precipitate

Explanation:

The solubility rules can be used to asses whether the reaction yields a precipitate(solid).

For this question:

  1. Most chlorides (Cl⁻) are soluble, except  silver (Ag⁺), lead (Pb²⁺), and mercury (Hg²⁺).
  2. Most hydroxides (OH⁻) are insoluble, except for sodium (Na⁺), potassium (K⁺), and some of those of calcium (Ca²⁺) and barium (Ba²⁺).

Notice that BaCl2 will be soluble due to the Cl-, and therefore will not be a precipitate.

NaOH is an exception to the rule, and since there is sodium, NaOH is soluble and not a precipitate.
