Question

The titration of a strong acid with a strong base is represented by plot _____ .

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is A

The titration of a strong acid with a strong base is a common experiment in analytical chemistry that results in a specific type of pH curve. This process involves the gradual addition of a strong base (like NaOH) to a strong acid (like HCl), and the pH of the solution is measured throughout the titration.

Let's examine each option to identify the correct plot:

The correct graph representing the titration of a strong acid with a strong base is typically characterized by the following features:

1. The curve starts at a low pH because the solution initially contains just the strong acid.
2. The pH gradually increases as the base is added.
3. There is a steep rise at the equivalence point where the amount of acid equals the amount of base, indicating a rapid transition due to the formation of water (neutral pH of 7).
4. Past the equivalence point, the pH levels off and continues to rise as more base is added.

By analyzing the provided options, the first image represents this behavior, as described:

• Starts with a low pH.
• Has a steep rise at the equivalence point near pH 7.
• Continues with a gentle rise as more base is added past the equivalence point.

Therefore, the correct plot for the titration of a strong acid with a strong base is the one represented by the first image.
