Is tea a colloid? why/why not? please explain it
Dear student ,
Filtered tea is a colloid and hence it is a heterogeneous mixture.
A colloid is a heterogeneous mixture. The size of the solutes in this mixture is so small that they cannot be seen individually with naked eyes, and seems to be distributed uniformly throughout the mixture. The solute particles do not settle down when the mixture is left undisturbed. This means that colloids are quite stable.
Colloids cannot be separated by the process of filtration. They can be separated by centrifugation. Filtered tea has all the properties listed above hence it is a heterogeneous mixture.
