hi, I'm studying chemical 2 in Korean school.

I wonder why colloid molecule has only one kind of electronic charge..

so, I ask my teacher... but... it's not clear

so, I don't know why it is any more.

anyway, why has colloid molecule only one kind of electronic charge??

Colloid is not a term we really use to describe individual molecules, but rather a system - where one substance is evenly dispersed throughout another.

So, I would not call fats or water colliodal molecules but I would call a glass of milk a colloid.

The molecules within a colloid are free to hold a charge, subject to the regular laws of chemistry, which can be stabilised by additives like detergents.
