What else can I help you with?
The point at which a substance becomes evenly distributed throughout the solution and the concentration gradient disappears is called what?
The point at which a substance becomes evenly distributed throughout the solution is called equilibrium.
What is a concentration gradient?
It is the difference in concentration (molecules of a solute per volume of solution) between two locations. Because of the motion of molecules, they are said to diffuse (move, spread) from an area of greater concentration to an area of lesser concentration. Some molecules are always moving in the opposite direction, but the overall trend is "down" the gradient until equilibrium is established between the two regions. And, generally, the larger the gradient or difference, the faster the rate of the diffusion.
What can you say about a solution when Qsp is greater than Ksp?
If Qsp is greater than Ksp, it means the solution is supersaturated with respect to the solute. This may lead to precipitation of excess solute until equilibrium is re-established.
What is a solution with a concentration above the equilibrium solubility called?
A solution with a concentration above the equilibrium solubility is called supersaturated. This means that the solution contains more solute than it should be able to hold at that given temperature.
How is the equilibrium changed in the water after salt is added?
When salt is added to water, the equilibrium of the system is disturbed due to the dissolution of the salt. This disruption leads to an increase in the concentration of ions in the solution, which can affect properties such as boiling point, freezing point, and osmotic pressure. Eventually, a new equilibrium is established between the dissolved salt and the water molecules.
The point at which a substance becomes evenly distributed throughout the solution and the concentration gradient disappears?
equilibrium
The point at which a substance becomes evenly distributed throughout the solution and the concentration gradient disappears is called what?
The point at which a substance becomes evenly distributed throughout the solution is called equilibrium.
When does osmotic equilibrium occur?
When the water potential gradient evens out, so that the water potential on eithersides of the partially permeable membrane is equal. Also, when something is placed in an isotonic solution ( a solution with the same waterpotential as the organism contains)
Calculating concentration gradient?
The gradient can be calculated by comparing the solute particles from one solution with another. Distance determines the gradient levels within the solution.
What are two ways you can change the concetration of a solution?
Adding more solute or adding more solvent
Solution equilibrium most likely exists in which type of solution?
Equilibrium is only found in a saturated solution, where the dissolved species and the undissolved species are in equilibrium with each other. In a dilute solution there is nothing that is undissolved, and so there is no equilibrium, and by definition a supersaturated solution is out of equilibrium and essentially has too much stuff dissolved in it (it will eventually return to equilibrium and some of the dissolved material will precipitate out).
50 g of potassium chloride (KCl) are added to 100 mL of water. All but 10 g of the KCl dissolves. Which equilibrium situation becomes established in the resulting solution?
The remaining 10 g of KCl forms a saturated solution in water, meaning the solution is in dynamic equilibrium with solid KCl dissolving and KCl ions re-crystallizing at the same rate. The resulting solution will contain both dissolved K+ and Cl- ions in equilibrium with undissolved KCl crystals.
How do isotonic solutions and equilibrium differ?
isotonic solution, equilibrium
What is solubility equilibrium?
Equilibrium solubility is how much of a certain solute is in solution when the system has reached equilibrium. For example, when something like silver chloride (AgCl) is placed in water, none of it goes into solution. But given some time, an equilibrium will be reached where a small amount of AgCl is in solution and is in equilibrium with the insoluble AgCl.
What is a concentration gradient?
It is the difference in concentration (molecules of a solute per volume of solution) between two locations. Because of the motion of molecules, they are said to diffuse (move, spread) from an area of greater concentration to an area of lesser concentration. Some molecules are always moving in the opposite direction, but the overall trend is "down" the gradient until equilibrium is established between the two regions. And, generally, the larger the gradient or difference, the faster the rate of the diffusion.
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in?
When the dissolving rate equals the rate at which molecules come out of solution, the solution is in a state of dynamic equilibrium. This means that the amount of solute dissolving is equal to the amount of solute precipitating out of solution, resulting in a stable concentration of solute.
What can you say about a solution when Qsp is greater than Ksp?
If Qsp is greater than Ksp, it means the solution is supersaturated with respect to the solute. This may lead to precipitation of excess solute until equilibrium is re-established.
