The dye take a look at observes emulsion droplets under a microscope soon after incorporating an oil-soluble dye. If the continual period is coloured and droplets are distinct, It's a W/O emulsion; if droplets are coloured and the continuous phase is evident, it's an O/W emulsion. The conductivity take a look at employs electrodes - if a bulb glows, it truly is an O/W emulsion, and Otherwise, it is a
