Oil and Water (Vinegar) Mixture


0

💚 Do you observe (see) layers?

0

💚 Does this mean the oil and water mix or not mix (separate)?

0

Are the oil molecules and water molecules attracted to each other?

Oil, Water (Vinegar) and Lecithin Mixture


0

💚 Do you observe (see) layers?

0

💚 Does this mean the oil and water mix or not mix (separate)?

0

Does this mean the oil molecules are attracted to the lecithin (emulsifier) molecules?

0

💚 Does this mean the water molecules are attracted to the lecithin (emulsifier) molecules?

Model

Nanoscale - Too small to see (atoms and molecules)


Now we are going to look at the oil and water (vinegar) mixtures at the nanoscale (molecules)
