Identify the homogeneous mixture(s) from the following.
P: Lemonade
Q: Soda
R: Sand water
Lemonade(P) and Soda(Q) are homogeneous mixtures as components are uniformly distributed and are indistinguishable from each other.
Sand water(R) is heterogeneous as the components of the mixture are not uniformly distributed in the mixture. If left undisturbed, the sand settles at the bottom and can be distinguished from the water.
As P and Q are homogeneous mixtures, hence option B is correct.
