The solubility of a substance is described as varying from essentially zero to:
AInfinity, or miscible
BExactly one mole
CExactly ten grams
DA fixed upper bound
Answer & Solution
Correct answer: A. Infinity, or miscible
1. Solubility spans an enormous range across substances.
2. The solubility of a substance can vary from essentially zero.
3. That zero end covers insoluble or sparingly soluble compounds.
4. At the other end solubility runs to infinity, which is miscible.
