I'm sure most of you are familiar with this solubility chart that's found on nearly every CWE tutorial: Solubility \| 31C water \| 21C water Aspirin \| 1g / 100 ml \| 1g / 300 ml Acetaminophen \| 1g / 70 ml \| 1g / 150 ml Codeine \| 1g / 2.3 ml \| 1g / 0.7 ml Has anyone else ever wondered why it states that codeine is more soluble in cold water than hot water? Surely this must be a mistake, or does codeine phosphate's chemistry somehow "magically" make it more soluble in cold water than hot. __________________ Hold my syringe as I kiss your girlfriend
