Question

which characteristic is not true about solutions? they can be filtered they contain dissolved particles they dont separate on standing they are homogeneous mixtures

Explanation:

A solution is a homogeneous mixture with dissolved particles (solute) in a solvent. The particles are too small to be filtered out (filtration separates larger, undissolved solids). Solutions don’t separate on standing (stable) and are homogeneous. So "They can be filtered" is not true.

Answer:

They can be filtered
