Questions tagged [immiscibility]

This tag should be used when asking questions about two or more liquids that cannot mix, for example, water and oil. This tag should not be used for cases where two liquids can be homogenized by mixing, for example, cold and hot water, or water with two different dissolved salts and densities.
