Question

Victor is making cake batter. When he added corn oil, fat-free milk, baking powder, and salt together, the oil and milk separated into two layers. To make a mixture that does not separate into oily and watery components, Victor should add ________ and stir the ingredients together.

Answer 1

Answer:

egg yolk

Explanation:

• In order to combine the oily and watery components which are immiscible ( unable to mix) Victor would require an emulsifier.
• An emulsifier is a substance which contains molecules with hydrophilic (water-loving) and hydrophobic ( water-repellent) ends.
• Emulsifiers allow substances like water and oil to become miscible (able to mix and form a single smooth emulsion).
• Egg yolk is an example of an emulsifier which is suitable to Victor's activity- making cake batter.
• The egg yolk will prevent the separation of oil and water components.
