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 comes out of solution the solution is in 'equilibrium'.
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
What is the chemical formula for household ammonia?
You could say ammonium hydroxide, but that is not quite correct in solution. NH3(aq) is sometimes used, but this is the equilibrium reaction. NH3 + H2O <<->> NH4(+) + OH(-)
Will lead II iodide be more or less soluble in a solution of 0.1M KI than it will be in pure water?
If KI is present in a solution and PbI2 is being dissolved in it, there will be a greater concentration of I, this will cause the equilibrium to shift left, away from the increase, according to Le Chatelier's Principle. Shifting the equilibrium left will result in a greater mass of solid PbI2. Therefore the solubility of PbI2 will decrease in a solution of KI.
What is true about a solution if the reaction quotient is less than the solubility product constant?
the reaction is at dynamic equilibrium.
What is homogeneous equilibria?
Homogeneous equilibrium occurs when all reactants and products are in the same physical state, such as all being in the gas phase or all being in solution. It is characterized by the forward and reverse reactions occurring at the same rate, resulting in a constant concentration of reactants and products. The equilibrium constant for homogeneous equilibria is defined based on concentrations of species in the same phase.

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 'equilibrium'.
Why is it significant to know whether a solution is saturated or u nsaturated?
If a solution is saturated you will not be able to dissolve any more of the material in that solution at that temperature. If the concentration of the dissolved material determines the reaction rate of a reaction you care about then you will need to adjust temperature or make other changes to speed it up. In contrast, if you have an unsaturated solution, you can dissolve more of the material in it and increase the reaction rate.
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.
A solution that is at equilibrium must be?
Saturated
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
What is a solution with a concentration above the equilibrium solubility called?
a supersaturated solution
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
