Questions & Step-by-Step Solutions
Which of the following indicators would be suitable for a strong acid-strong base titration?
Step 1: Understand what a titration is. A titration is a method used to determine the concentration of a solution by adding a solution of known concentration until a reaction is complete.
Step 2: Identify what a strong acid and a strong base are. A strong acid completely dissociates in water (like hydrochloric acid), and a strong base completely dissociates in water (like sodium hydroxide).
Step 3: Know that during a strong acid-strong base titration, the pH of the solution will change rapidly around the point where the acid and base neutralize each other.
Step 4: Learn about pH indicators. These are substances that change color at a specific pH level, helping to identify when the reaction is complete.
Step 5: Find out what pH range is important for strong acid-strong base titrations. The equivalence point (where the acid and base neutralize) is around pH 7.
Step 6: Look for an indicator that changes color around pH 7. Bromothymol blue is one such indicator, as it changes color at this pH level.
Step 7: Conclude that bromothymol blue is suitable for strong acid-strong base titrations because it provides a clear visual cue when the pH is around neutral.
