Why are terms like 'insoluble' and 'very highly soluble' considered less effective for quantitative work?
Why are terms like 'insoluble' and 'very highly soluble' considered less effective for quantitative work?
- They provide specific numerical values.
- They are imprecise and non-specific. (correct)
- They relate to the chemical structure of solutes.
- They are frequently used in quantitative analyses.

Study Notes
Expressions of Solubility
- Solubility of a solute in a solvent can be expressed quantitatively using several concentration units.
- Solubility can also be expressed in parts per parts of solvent, like parts per million (ppm).
- The British Pharmacopoeia and similar compendia use the terms 'insoluble', 'very highly soluble', and 'soluble' to described solubility.
- These terms are imprecise and not very useful for quantitative work.
- Specific concentration terms should be used for quantitative work.
