315 views

Caffeine solubility in water depends on the temperature. At room temperature (25°C or 77°F), about 2 grams of caffeine can dissolve in 100 milliliters of water. This solubility increases significantly with the temperature; for instance, at 80°C (176°F), around 18 grams of caffeine can be dissolved in 100 milliliters of water. Thus, if you're looking to dissolve more caffeine, using hot water is substantially more effective.
