Chemistry => Solutions => Solubility
A mixture corresponds to joining two or more substances, depending on the behavior of the mixture, it can be said that the substances are miscible, immiscible, or partially miscible.
Immiscible refers to the fact that regardless of the proportion of the substances we will have two phases since the substances do not mix.
Partially miscible means that the substances mix depending on the proportion between them.
Miscible refers to the fact that regardless of the proportion, the substances will always be mixed, therefore we will see a single phase.
Therefore, the correct answer will be: Miscible
