Question:- Black coffee is a homogeneous mixture. True False
Answer:- It is a true statement.
A solution such as black coffee is a homogeneous mixture. Homogeneous mixtures composed of dissolved solutes in a solvent are known as solutions. These soluble compounds, such as caffeine and oils extracted from the coffee beans, include tannins.
The soluble coffee solids dissolve and disperse homogeneously into the water medium as it is brewed with hot water. This results in a one-phase solution with uniform composition and presentation all over. Instead of being isolated, the dissolved coffee compounds are distributed equally at a molecular level.
In contrast to a heterogeneous mixture, solution does not segregate on its own and the composition is even throughout. In a solution of black coffee, there are no observable particles or stratification. Any insoluble materials are eliminated, and there remain in the water solvent only dissolved coffee solutes. This homogeneity at the microscopic level makes black coffee a Homogeneous mixture.
Thus, even though black coffee first seems to be dull and dark it is a true solution . The black color is the result of uniform dispersion of coffee compounds, not from particles that are suspended in it. In its ideal state, black coffee follows the definition of a homogeneous mixture because it has uniform qualities in terms of appearance and molecular composition.
