where salt is water follows! Why?
WHere salt goes water follows! why?
Salt absorbs moisture from the air.
Salt, dissolved in water, flows from land to the oceans. Water carries it there.
If you are in biology, this refers to diffusion across a cell boundry. Osmotic pressure will be moving water across any cell membrane from the low concentration to the high concentration (salt) side. Diffusion tends to move water to where it is most needed to make the concentrations equal. Put salt on one side of a membrane, water moves across the membrane to dilute the salty side.
The phrase "where salt is, water follows" or "where salt goes, water follows" is based on the principle of osmosis.
Osmosis is the movement of solvent molecules, in this case water, across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In simpler terms, it is the movement of water from a less salty solution to a more salty solution.
When salt, or any solute, is dissolved in water, the concentration of solute particles increases. This creates a concentration gradient, with higher solute concentration on one side of the membrane and lower solute concentration on the other side. Water molecules then move across the membrane in an attempt to equalize the concentration on both sides.
So, when salt is present in water, the higher concentration of salt molecules attracts water molecules and pulls them towards the salt. This causes the water to "follow" the salt and move towards the area with a higher salt concentration.
In summary, the movement of water following salt is a result of osmosis, where water moves from areas of low solute concentration to high solute concentration in order to balance the concentration on both sides of a membrane.
