Dissolving caffeine in room temperature water

Click For Summary
SUMMARY

The discussion focuses on the challenges of dissolving 500mg of caffeine in 10ml of water, where the solution turns into a paste upon cooling. Heating the water initially aids in dissolution, but the caffeine reverts to a paste as the temperature drops. Participants suggest researching the solubility of caffeine in water as a function of temperature and using carbonated water to enhance solubility due to its acidic nature, which helps ionize caffeine.

PREREQUISITES
  • Understanding of caffeine's chemical properties
  • Knowledge of solubility principles
  • Familiarity with temperature effects on solubility
  • Basic chemistry of acids and bases
NEXT STEPS
  • Research the solubility of caffeine in water at various temperatures
  • Explore the effects of using carbonated water on caffeine dissolution
  • Investigate other substances that may enhance caffeine solubility
  • Learn about the ionization process of basic compounds in acidic solutions
USEFUL FOR

Chemists, food scientists, beverage formulators, and anyone interested in improving the solubility of caffeine in aqueous solutions.

Hello everyone,

I have been trying to dissolve caffeine in water for a few days now.
I am trying to dissolve approx. 500mg of caffeine in approx. 10ml of water, but I am encountering the problem that the solution turns into a paste. If I heat the water beforehand, the caffeine dissolves well at first, but then quickly turns back into a paste as soon as the solution cools down.
Are there any processes or substances that improve the solubility of caffeine in water?
I look forward to any answers. :)

Have you tried directly searching for an answer? Such as search terms increasing solubility of caffeine in water? After, of course, finding the solubility of caffeine in water as a function of temperature.

At PF, we want to help you find answers after you have made your own attempt.
 
try using a carbonated water. It is acidic and will cause the basic caffeine to ionize and increase its solubility in water.
