Question: In a titration involving a strong acid and a strong base, what is the expected pH at the equivalence point?

Options:

Correct Answer: 7

Solution:

At the equivalence point of a titration between a strong acid and a strong base, the pH is expected to be 7, indicating a neutral solution.

In a titration involving a strong acid and a strong base, what is the expected pH at the equivalence point?

Step 1: Understand what a titration is. It is a method used to determine the concentration of a solution by adding a solution of known concentration until the reaction is complete.
Step 2: Identify the substances 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, meaning they completely neutralize each other.
Step 4: Recognize what happens at the equivalence point. When a strong acid reacts with a strong base, they produce water and a salt.
Step 5: Determine the pH at the equivalence point. For strong acids and strong bases, the resulting solution is neutral, which has a pH of 7.

Titration – A technique used to determine the concentration of a solution by reacting it with a solution of known concentration.
Equivalence Point – The point in a titration where the amount of titrant added is stoichiometrically equivalent to the amount of substance in the sample.
pH at Equivalence Point – For strong acid-strong base titrations, the pH at the equivalence point is typically 7, indicating a neutral solution.
