Ice water mixture is a heterogeneous system but still it is a pure substance. Why?
Answers
Answer:
Homogeneous mixtures are uniform or consistent in their phase and composition. In a homogeneous mixture, the elements forming the mixture do not remain physically distinct. On the other hand, heterogeneous mixtures are not uniform or consistent in their phase and/ or composition. The elements forming the mixture remain physically distinct.
Both the ice and the water are H2O, but they are in two different phases.
A homogeneous mixture has the same uniform appearance and composition throughout, and as is plainly visible in the case of the ice/water mixture, its composition is not uniform.
Ice and water are not actually the same thing, as demonstrated by the fact that we use the two different words "ice" and "water" to describe them.
If all the ice were to melt and there were no impurities present, it would not be a mixture at all but would just be the compound H2O.
This means it is not possible to have a homogeneous mixture of ice and water, because if you "dissolve" the ice in the water it is not actually an aqueous solution, but a pure liquid.
