What do you call this? (Topic : Emulsion)?
In the lab, we mixed ethanol, water, and oil. Thus, emulsion is observed.
We placed a few drops of the mixture and we have seen bubbles of oil in the microscope.
What do you call those bubbles? (I believe there's an exact term to call it)

The problem here is that, although some of the oil, water and ethanol are in the right proportions
to form a micro-emulsion, there is some free oil present, and that is what you are seeing. If
you add slightly more ethanol, the big oil droplets will go away.
What makes it a micro-emulsion is that there are droplets, but they are smaller than the
wavelengths of visible light, and so appear transparent, or very slightly hazzy.
