If a pinch of flour is placed in water, does it form a coarse suspension, colloidal dispersion, or true solution? What about pepper? I thought both would be a coarse suspension

Answer 1

Some of the flour goes into solution, some forms a course suspension and there are some particles small enough to form a colloidal suspension. I think pepper forms a suspension.

Answer 2

Would non-dairy creamer also be a colloidal dispersion when placed in water?
