The concentration of the salt solution does NOT change- it is saturated.
A saturated solution is made when you have added so much solute that no more dissolves. The amount of solute needed to make a saturated solution will change with the temperature of the solution.
A saturated solution has a solute that is at its maximum concentration. At this point, no more solute can be dissolved at the current temperature. The dissolved and undissolved solutes are at equilibrium in the saturated solution.
Solution provided the solution is not saturated.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
The formula to calculate the change in pH when a strong acid is added to a buffer solution is pH -log(H/HA), where H is the concentration of hydrogen ions and HA is the concentration of the weak acid in the buffer solution.
The concentration increases as solid solute drink mix is added to a solvent (such as water) because more solute particles are being added to the same volume of solution. The concentration is directly proportional to the amount of solute per unit volume of solution.
If more solute is added to the solution and the solute remains undissolved, then you know that solution is saturated.
A saturated solution is a mixture in which no more solute can dissolve in the solvent at a particular temperature. It is at its maximum concentration level and any additional solute added will not dissolve.
You can determine if the solution is saturated by adding a small amount of salt to the solution. If the salt dissolves, the solution is unsaturated. If the added salt does not dissolve and collects at the bottom of the container, the solution is saturated.
From your question it is impossible to tell. A salt-water solution can be unsaturated or saturated depending on how much salt was added.
When a solution is saturated, it means that it has reached its maximum capacity to dissolve solute at a given temperature. Any extra solute added will not dissolve and will remain as a solid at the bottom of the container.
A saturated solution is a solution that no more solute will dissolve. Once the solution is saturated, any more solute that is added will not dissolve.
