Does coffee powder mix with water?

Yes, coffee powder mixes with water. It doesn't dissolve completely, but it does suspend in the water to create a coffee beverage.

Here's why:

* Coffee is a mixture, not a solution: Coffee powder contains many different compounds, including caffeine, tannins, and oils. Some of these dissolve in water, while others do not.

* Suspension: The undissolved particles remain suspended in the water, creating the characteristic cloudy appearance of coffee.

* Extraction: When coffee is brewed, hot water extracts soluble compounds from the coffee grounds. This is why the longer the brew time, the stronger the coffee.

So, while coffee powder doesn't fully dissolve, it does mix with water to create a flavorful and enjoyable drink.
