To determine the suitability of an indicator with a pKa of 5 for various titrations, we need to analyze the pH at the equivalence point of each titration. The indicator will change color around its pKa value, which is typically within one pH unit above or below the pKa. Therefore, the indicator will be suitable for titrations where the pH at the equivalence point is close to 5. ### Step-by-Step Solution: 1. **Understand the pKa of the Indicator**: - The given pKa of the indicator is 5. This means that the indicator will change color around this pH value, specifically between pH 4 and pH 6. 2. **Analyze Each Titration**: ...
