Answer :
Answer:
no precipitate
Explanation:
The solubility rules can be used to asses whether the reaction yields a precipitate(solid).
For this question:
- Most chlorides (Cl⁻) are soluble, except silver (Ag⁺), lead (Pb²⁺), and mercury (Hg²⁺).
- 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.
