The part of a solution that is present in the larger amount is the _________________________________________. 5. A(n) ____________________________________ is a mixture containing small, undissolved particles that do not settle out, but are large enough to scatter light. 6. A mixture in which particles can be seen and easily separated by settling or filtration is called a(n) ___________________________________. 7.
