They can be used for the estimation of specific substances, possibly present at very low concentration, in the presence of outher, chemically similar, substances.
An isotonic solution is one in which the ionic environment is similar to that of the cytoplasm. Hence, when a cell is placed in an isotonic solution, there is no net diffusion of water into or out of the cell. The cell remains intact.
Mixtures are formed from two or more substances.
Diffusion-movement of substances from a region of higher concentration to a region of lower concentration down a concentration gradient. Osmosis (also similar to diffusion) - movement of water molecules from a region of higher water potential to a region of lower water potential down a water potential gradient:)

The processes that can move a solute against its concentration gradient are active transport. All cells are enclosed by a plasma membrane that is similar in structure and function.

We generally use the term "tonic" when referring to the effects of osmosis across a real biological membrane. Osmosis is the movement of water across a membrane. We usually have osmosis when the concentration of solutes on each side of the membrane are different so water diffuses from the side with lower solute concentration to the side with higher concentration and this usually continues until we have equilibrium and no more water diffuses across. This environment is called an isotonic environment. ("iso" is Greek for similar or equal)
