I know about chemical and physical differences between Solution and Colloid, but I can't find anywhere what is the right naming convention for Colloid substances. Let me explain: For Solution we have: Solute dissolved in Solvent called a Solution. For Colloid we have: "1st substance" dispersed in "2nd substance" called a Colloid. So is there a proper chemical definition for 1st and 2nd substances? Definitely it can't be Solute and Solvent, since it is not a Solution. I ask because write now I have to write in my work: "Substance in which the dispersion happens" or "Substance Dispersed" every time, which is very cumbersome. Regards, Qshadow.
