What is the effect of adding a base to a solution of a weak acid?

Step 1: Understand that a weak acid is a substance that partially dissociates in water, meaning it does not completely break apart into ions.
Step 2: Recognize that a base is a substance that can accept protons (H+ ions) from acids.
Step 3: When you add a base to a solution of a weak acid, the base reacts with some of the acid's H+ ions.
Step 4: This reaction reduces the number of free H+ ions in the solution, which decreases the acidity.
Step 5: As the acidity decreases, the pH of the solution increases, making it less acidic and more neutral.
