Q: In a strong acid-strong base titration, what is the expected pH at the equivalence point?
Solution: At the equivalence point of a strong acid-strong base titration, the pH is expected to be 7 due to the complete neutralization of the acid and base.
Steps: 6
Step 1: Understand what a titration is. It is a method to determine the concentration of an acid or base by reacting it with a base or acid of known concentration.
Step 2: Identify the types of solutions involved. In this case, we have a strong acid (like hydrochloric acid) and a strong base (like sodium hydroxide).
Step 3: Know what the equivalence point is. This is the point in the titration where the amount of acid equals the amount of base, resulting in complete neutralization.
Step 4: Recognize what happens at the equivalence point. The strong acid and strong base completely react with each other to form water and a salt.
Step 5: Understand the pH scale. A pH of 7 is considered neutral, meaning there is neither excess acid nor excess base in the solution.
Step 6: Conclude that at the equivalence point of a strong acid-strong base titration, the pH is expected to be 7 because the solution is neutral.
