suppose we have a substance that is hydrophobic/hydrophilic and also has some charge on it surface(negative or positive) disspersed in water. if we add some salt different kinds possible(NaCl NaNO3 NaSCN). What is the effect of hydrophobicity and surface charge on Electrophoretic mobility?

Salts will cause the substance to adopt a more compact structure with the hydrophobic bits internalized and the hydrophilic bits exposed. It should move faster/farther.

but i want a explanation for the order of salts, which one acts more strongly?, and what is the difference between hydrophilic/hydrophobic dispersed substance with negetive/positive charge on its surface regarding their stability,how they interact with diffrent salts.
