This page provides supplementary chemical data on caffeine. ... Solubility in water. 2.17 g/100 mL (25 °C) 18.0 g/100 mL (80 °C) ... 192 mg/kg (rat, oral) [3]
[7] [8] Caffeine is moderately soluble in water at room temperature (2 g/100 mL), but quickly soluble in boiling water (66 g/100 mL). [197] It is also moderately soluble in ethanol (1.5 g/100 mL). [197] It is weakly basic (pK a of conjugate acid = ~0.6) requiring strong acid to protonate it. [198]
For example, 1 g (0.035 oz) of caffeine dissolves in 46 mL (1.6 US fl oz) of water at room temperature, and 5.5 mL (0.19 US fl oz) at 80 °C (176 °F). [22] The xanthine alkaloids are odorless, but have a bitter taste in water, which is masked by organic acids present in green coffee. [citation needed]
A serving of G Fuel contains 140 to 150 mg of caffeine. [ 4 ] [ 5 ] G Fuel is available in multiple flavors, typically fruit-based, such as fruit punch , green apple , and lemon lime . In addition, G Fuel often collaborates with film production companies, [ 6 ] [ 7 ] [ 8 ] game studios, [ 9 ] [ 10 ] video game media companies , [ 11 ] and ...
Boiling tea leaves in water extracts the tannins, theobromine, and caffeine out of the leaves and into the water, as an example of a solid-liquid extraction. Decaffeination of tea and coffee is also an example of an extraction, where the caffeine molecules are removed from the tea leaves or coffee beans, often utilising supercritical fluid ...

K ow, being a type of partition coefficient, serves as a measure of the relationship between lipophilicity (fat solubility) and hydrophilicity (water solubility) of a substance. The value is greater than one if a substance is more soluble in fat-like solvents such as n-octanol, and less than one if it is more soluble in water. [citation needed]
