The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
[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]

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Cola has 22 mg in an 8-oz. serving, and while that is much less than coffee, soft drinks are typically served in 12-oz. cans or 20-oz. bottles, so here, too, the caffeine can add up. As for energy ...
The U.S. Food and Drug Administration (FDA) says that most people can tolerate up to 400 milligrams of coffee a day—that lines up to between two and three 12 oz cups of the good stuff each day ...
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]
