What is the difference between a strong acid and a concentrated acid?
AStrong describes how much was added
BStrong describes how far it ionises
CStrong describes how hot it must be
DStrong describes how it tastes
Answer & Solution
Correct answer: B. Strong describes how far it ionises
1. Strong and weak describe how completely an acid ionises when it is put into water.
2. A strong acid ionises almost completely, a weak acid only ionises to a small extent.
3. Concentrated and dilute describe how much acid was added to the solvent.
4. So a strong acid can be prepared as a dilute solution, and a weak acid can be concentrated.
5. Confusing the two is the usual mistake, which is why the amount added is the wrong answer here.
