When ammonium chloride dissolves what happen to the temperature?
The temperature of the solution will decrease. The dissolving of NH4Cl in water is endothermic.
A KNO3 solution containing 45 g of KNO3 per 100g of water is cooled from 40 degrees celciuswhat will happen during cooling?
As the KNO3 solution cools, solubility of KNO3 decreases with temperature, leading to the formation of excess KNO3 crystals. These crystals will start to precipitate out of the solution as it cools. If the cooling continues, more crystals will form until the solution becomes saturated at a lower temperature.
A solution is saturated with dissolved minerals - what will happen if 50 percent of the water in the solution evaporated?
When 50 percent of the water evaporates from a saturated solution, the concentration of the dissolved minerals will increase as the same amount of minerals now remains in a smaller volume of water. This may lead to the precipitation of some minerals, resulting in the formation of solid crystals at the bottom of the container.
When does soil become more liquid?
Soil can become more liquid when it absorbs excess water, causing a decrease in viscosity and turning it into mud or slurry. This can happen when there is heavy rainfall, snowmelt, or over-irrigation, leading to saturated soil conditions.
What will happen if a small amount of sodium hydroxide is added to a 0.1 M solution of ammonia?
The sodium hydroxide will react with ammonia to form a complex called sodamide and water. This reaction will increase the pH of the solution and result in the formation of a new compound.
What will happen if a saturated solution of copper chloride is cooled?
If a saturated solution of copper chloride is cooled, the solubility of the compound will decrease, causing excess copper chloride to precipitate out of the solution in the form of solid crystals. This process is known as crystallization.
When ammonium chloride dissolves what happen to the temperature?
The temperature of the solution will decrease. The dissolving of NH4Cl in water is endothermic.
What would happen if a hot saturated solution was cooled slowly?
Crystallisation
Can happen to a super saturated solution?
the solute can re-form as a solid
What would happen if a hot saturated solution was cooled quickly?
If a hot saturated solution is cooled quickly, the solubility of the solute decreases with temperature, causing excess solute to precipitate out of solution. This rapid cooling can result in the formation of larger crystals or a higher amount of crystals in the solution.
Explain how a solution can be both dilute and saturated?
A solution can be dilute and saturated if there is a small amount of solute relative to the amount of solvent, making it dilute, but all of the solvent has already dissolved the maximum amount of solute possible at that temperature, making it saturated. This can happen when the solute has low solubility in the solvent or if the temperature decreases after the solution has been prepared.
What happen to salt particles when they are placed in water?
They dissolve until the solution is saturated.
What would happen if you were to take a saturated solution at a certain temperature and cool it slowly?
the concentration of this solution is going to reduce.< Lets assume that the solution is comprised of water and salt> Then the water at a certain temperature begins to evaporate unlike the salt. at the end of the process, yes we agree that the solution has finally come to a room temperature, but concentration was lost during cooling. I mean that the solution becomes less concentrated
What solution contains more solute than predicted at a given temperature?
A supersaturated solution contains more solute than predicted at a given temperature. This can happen when a solution is prepared with more solute than can normally dissolve in that solvent at that temperature, creating a metastable state where the excess solute remains dissolved until disturbed.
What should happen to the temperature if the kinetic energy is reduced?
It will decrease
What will happen if you keep adding sugar to a given amount of water at room temperature?
Eventually no more will dissolve. We say the solution has become saturated.
What may happen when a material loses heat?
The temperature of this material decrease.
