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).
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 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.
What evidence do you have that the equilibrium shifted when saturated potassium nitrate solution was cooled?
The evidence that the equilibrium shifted when a saturated potassium nitrate solution was cooled is the precipitation of potassium nitrate crystals. Cooling the solution causes a decrease in solubility, leading to excess solute (potassium nitrate) to precipitate out of the solution. This indicates that the equilibrium has shifted towards the solid phase as a result of the change in temperature.
How does Le Chatelier's Principle apply to changes in an aqueous solution?
Le Chatelier's Principle states that when a system in equilibrium is disturbed, it will shift to counteract the disturbance. In an aqueous solution, this means that if you change the concentration of reactants or products, the system will adjust to restore equilibrium. For example, if you add more reactants, the system will shift to produce more products to balance it out.
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.
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
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
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.
What are examples are equilibrium?
Every physical phenomenon is an example of equilibrium; whenever there is conservation ,if you look closer, there is equilibrium. The action reaction principle is one example.
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.
