### Why does a solution of potassium chloride conduct electricity?

A solution of potassium chloride in an ionization
promotingsolvent such as water conducts electricity because the
positive and negative ions in potassium chloride in such a
solutionare separated from each other by a sufficient distance that
they can move in opposite directions in a electric field imposed on
the solution by two (or more) electrodes maintained at a potential
difference by means external to the solution.

###### Asked in Science

### Which Criteria used to distinguish between true solution and colloids as no residue is left on filter paper on filtration?

In true solution the molecules of the solute get equally
distributed throughout the solvent in the atomic level i.e. at the
distance of diameter of an atom. While in colloides the molecules
are not mixed in such state. So, using this as a principal to
distinguish between colloide & solution. We can centrifuge the
two mixtures to distinguish the colooide & solution.

### What is meant by diffusion gradient?

a gradual change in the concentration of solutes in a solution
as a function of distance through a solution. 2. the gradual
difference in the concentration of solutes in a solution between
two regions. In biology, a gradient results from an unequal
distribution of ions across the cell membrane. When this happens,
solutes move along a concentration gradient. This kind of movement
is called diffusion.
