If fat is present a mixture of ethanol and water becomes Cloudy white in colour.
Explanation:
- Water is insoluble in lipids, yet ethanol is soluble in lipids (alcohol). When lipids are dissolved in ethanol and then added to water, they produce small scattered droplets in the water.
- This is referred to as an emulsion. Ethanol aids in the dissolution and dispersion of lipids in water in the form of droplets, however pre-mixing with water does not aid in the formation of sufficiently small droplets.
- These droplets scatter light as it flows through the water, giving it a Cloudy white and hazy appearance.
