The pH of the solution will be **greater than 7**. Here's why:* **Reaction:** The reaction between HCl (a strong acid) and Ba(OH)₂ (a strong base) will produce salt (BaCl₂) and water.* **Neutralization:** The reaction will neutralize some of the acid and base, but since the moles of base are less than the moles of acid, there will be some excess acid remaining.* **pH:** The presence of excess acid will make the solution acidic, resulting in a pH greater than 7.
