Which of the following is the strongest acid? The salt that would most likely have a solubility product expression of Ksp is:
Understand the Problem
The question is asking which of the listed acids is the strongest based on their given pKa values, along with identifying a salt likely to have a specific solubility product expression.
Answer
Phosphoric acid; BaSO4
The strongest acid is Phosphoric acid with the lowest pKa value of 2.12. The salt that would most likely have a solubility product expression of Ksp is BaSO4 due to its low solubility.
Answer for screen readers
The strongest acid is Phosphoric acid with the lowest pKa value of 2.12. The salt that would most likely have a solubility product expression of Ksp is BaSO4 due to its low solubility.
More Information
Phosphoric acid's pKa of 2.12 makes it the strongest among the options, influencing its reactivity. BaSO4's low solubility in water is characteristic of salts that have established Ksp expressions, making it a prime candidate.
Tips
Remember that lower pKa values indicate stronger acids. For solubility product expressions, focus on salts with known low solubility.
