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 does the rate of dissolution and crystallization compare at equilibrium?
At equilibrium, the rate of dissolution is equal to the rate of crystallization. This means that the amount of solute dissolving is the same as the amount of solute precipitating out of solution, leading to a dynamic equilibrium where there is no net change in the concentration of the solution.
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 the dissolving rate equals the rates at which molecules come out of solution the solution is in?
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
How can you describe the equilibrium in a saturated solution?
No. A saturated solution is still in equilibrium. If you bring it into contact with more of the solute, the concentration will remain the same. Solute will precipitate out at the same rate that more solute dissolves into the solution. An unstable equilibrium would be a supersaturated solution. In a supersaturated solution, more of the solute is in solution that would be equilibrium with the solid solute (or gas if you are dissolving gas for example). An example that many people are familiar with is dissolving a lot of sugar into hot water. As it cools down, the solution becomes supersaturated. As long as there is nothing for the sugar to nucleate on , the sugar can remain in solution indefinitely. If you hang a string in the solution, the sugar will start crystalizing on the string, forming "rock candy."
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).
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.
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.
A solution in which the dissolved solute is in equilibrium with undissolved solute?
A saturated solution.
What particles are evenly dispersed or distributed in solution what condition is the solution said to be in?
equilibrium
What is an example of a solution that is in equilibrium?
A simple example of a solution in equilibrium is a saturated salt solution, where the rate of salt dissolving is equal to the rate of salt crystallizing out of the solution, resulting in a dynamic equilibrium where the concentration of salt remains constant.
Cell that contains 50 percent water is placed in a solution that is 30 percent water The cell and the solution will reach equilibrium when they both contain how much water?
The cell and the solution will reach equilibrium when they both contain 40% water. At equilibrium, the water will flow from the region of higher concentration (50% in the cell) to the region of lower concentration (30% in the solution) until the concentrations are equal.
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.
What is the equilibrium constant of acetic acid in a solution at a given temperature?
The equilibrium constant of acetic acid in a solution at a given temperature is a measure of the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium. It is denoted by the symbol Kc.
Why is the equilibrium price stable and therefore must be allowed to stay?
It must be less than the equilibrium price
What is a factor that must be present if a system is to be considered to be in a state of equilibrium?
Balance is a factor that must be present if a system is in a state of equilibrium.
