Two acids are at the same concentration. What does the stronger one produce?
AA lower hydronium ion concentration
BA higher hydronium ion concentration
CAn identical hydronium concentration
DNo hydronium ions whatsoever
Answer & Solution
Correct answer: B. A higher hydronium ion concentration
1. At equal concentration the two solutions start with the same amount of acid.
2. The stronger acid ionizes to a greater extent, so more of it comes apart.
3. That releases a higher concentration of hydronium ions.
4. This is why a strong and a weak acid of the same molarity give different pH readings.
