Methodology:
A known amount of pure pentachlorophenol was added to cold water. Then, the temperature was raised slowly with agitation until dissolution was complete.
Sample Information:
- Source and purity not specified.
- No specifications given.
Measurement Errors:
Mass concentration (m/v) (1): <6% *.
System Components:
- Pentachlorophenol, $\ce{ C6HCl5O }$; [87-86-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
