What else can I help you with?
How does the instant ice trick work?
A warm, saturated sodium acetate solution is allowed to cool. At the lower temperature the solution is supersaturated, meaning that more of a salt is dissolved in the water than would normally be possible. I the solution is disturbed the sodium acetate crystallizes instantly.
What is the relationship between solute solvent solution saturated unsaturated and supersaturated?
A solute dissolves in a solvent to form a solution; all the time that more of the solute can be dissolved it is unsaturated, but once the solution can hold no more of the solute it has become saturated.
What is HgHe10?
Mercury helide (not halide). Extremely unstable synthetic compound that rapidly and readily releases its helium.
What is the dependent variable of Does stirring a solution make salt dissolve more rapidly?
The dependent variable is the rate of salt dissolution in the solution.
Why honey dissolve more rapidly in hot water than in cold water?
Honey is a supersaturated solution, meaning it contains more dissolved solute (sugar) than a saturated solution at that temperature. When honey is added to hot water, the higher temperature causes the molecules to move faster, increasing the speed of the dissolution process. In cold water, the slower molecular movement makes it harder for the sugar molecules in honey to break apart and dissolve.
What solutions are very unstable?
One example of a solution that is very unstable is a supersaturated solution, where the solute is present at a concentration higher than its equilibrium solubility. Any disturbance, such as adding a crystal of the solute or shaking the solution, can cause the excess solute to rapidly crystallize out of solution. Another example is a metastable solution, which is on the verge of precipitating out the solute, especially under slight changes in temperature or pressure.
What is super saturation?
Supersaturated = Being more concentrated than normally possible and therefore not in equilibrium.
How is dry ice formed when sodium acetate is added to water?
Dry ice is not formed in this instance.Dry ice is solid carbon dioxide. The phenomenon involving sodium acetate is colloquially called hot ice. Simply adding sodium acetate to water will not produce this. You need to create a supersaturated solution. You add sodium acetate to water untill it cannot dissolve any more, and then cool the solution. Now you have an unstable solution that has more dissolved sodium acetate than it could normally hold. If it is disturbed, the sodium acetate will sponaneously crystallize.

How do you form a supersaturated solution?
Most often, by preparing a saturated solution of a substance in a solvent in which the solubility of the substance increases with temperature, then lowering the temperature while taking care to avoid agitation of or the intrusion of solids into the solution.

What happens when unstable air is forced to rise?
When unstable air is forced to rise, it continues to rise rapidly due to its buoyancy. As it rises, it expands, cools, and condenses, leading to the formation of clouds, precipitation, and potentially severe weather such as thunderstorms. This process is known as convection.
Under what conditions do thunderstorms form?
Thunderstorms form when warm, moist air rises rapidly into the atmosphere, creating strong updrafts. As the air rises, it cools and condenses, forming cumulonimbus clouds. If the atmosphere is unstable and moist enough, these conditions can lead to the development of thunderstorms with lightning, thunder, heavy rain, and sometimes hail.
