Answer 2

The phase system of completely miscible liquids is called emulsions.

Explanation:

Dry gum method/ Continental Method

• This method is used in the preparation of emulsions.
• Here, the oil is firstly triturated with gum(acacia) with the addition of a small amount of water.
• The mixture is continually triturated with the help of a mortar and pestle. This will continue until a "cracking" sound is heard the mixture appears as a creamy white liquid.
• This results in the formation of primary emulsion. The remaining water is slowly added in it resulting in the formation of a final emulsion.
