Physical aspects - Preparation of emulsions
7 important questions on Physical aspects - Preparation of emulsions
Why are emulsions meta-stable?
What is the Gibbs free energy when creating an interface or reducing an interface?
Reducing --> G is negative, process will occur spontaneously
What is the surface tension?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What happens when you decrease the surface tension?
How can the interfacial/surface tension be reduced and what does it result in?
What happens when a surfactant is added to water? And in oil?
Oil --> hydrophobic tails are present in the oil.
What changes in the Gibbs free energy when surfactants are added?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
