what is a colloid oncotic pressure?

it is the osmotic pressure of colloid solution

1 of 5

What is dialysis?

diffusion of small molecules and ions from the colloid across the dialysation membrane eg cellophane which is permeable to small molecules and not colloid perticlaes

2 of 5

what happens when the lysosphere destabilizes (solvation layer which includes water molecules and hydrated ions)?

The colloid particles will aggregate to form a bigger particle and precipitate out. Salting out effect when the salt ions compete with the water molecules destabilizing it.

what is a protective colloid?

A protective colloid are substances that form a hydrophilic colloid solution stabilizing the hydrophobic colloid particles.

4 of 5

which is not true?

surfactants are compounds that increase surface tension (adhesive and cohesive forces)
