is colloid a homogeneous mixture
I am currently in a chemistry 101 class and my professor adamantly believe that colloids fall under heterogenous mixtures only. I have researched on a few definitions of colloids and some sources say that it is a heterogenous mixture, others say its a homogenous mixture. And some even say that it is both. Even the wikipedia source is confusing because under colloids it is considered a heterogenous mixture but when you look at the definition of mixtures and the different kinds, colloids (or colloidal dispensions are referred to as homogenous) fall under homogenous mixture.
