How do drink crystals dissolve?
When drink crystals are mixed with water, the molecules in the crystal distribute themselves throughout the water due to the process of diffusion. This causes the crystal to break down and dissolve into the water until it forms a homogenous mixture.
Which substance will sink in glycerin?
When poured into water glycerol also a liquid falls to the bottom of the beaker
A student dissolves 10 grams of salt in a beaker with 1 liter of water how can the student get the salt back?
The student can retrieve the salt by evaporating the water. They can do this by heating the solution in the beaker until all the water evaporates, leaving behind the salt. The salt can then be scraped or collected from the bottom of the beaker.
What effect did the addition of sugar to Beaker B and salt to Beaker C have on the freezing point of the water in these beakers?
The addition of sugar to Beaker B lowered the freezing point of the water, while the addition of salt to Beaker C also lowered the freezing point of the water. This is because both sugar and salt act as solutes that disrupt the formation of ice crystals and reduce the freezing point of the solution.
What Two identical beakers are both equally filled with a liquid. Beaker A contains water. Beaker B contains a liquid that is denser than water. Which statement is true?
Beaker B, which contains the denser liquid, will exert more pressure at the bottom compared to Beaker A filled with water, due to the greater density of the liquid. Consequently, if both beakers are identical in size and shape and filled to the same height, the pressure exerted by the liquid in Beaker B will be greater than that in Beaker A.
What type of matter is in a beaker that has chloride crystals and water?
A pure substance
What will happen to dye crystals initially in the bottom of a beaker of water over a long period of time?
The dye crystals will dissolve in the water over time, spreading evenly throughout the solution. This process is known as diffusion, where particles move from an area of higher concentration to lower concentration until reaching equilibrium.
The liquid on top of material deposited by settling or centrifugation?
Let's define the conditions more specifically. You have a beaker of pure water at room temperature into which you pour table salt (NaCl). At first, all the salt dissolves into Na+ and Cl- ions. After a certain amount of salt is added, you notice that NaCl is precipitates from the water and settles on the bottom of the beaker. At this time, the water above the salt crystals still contains dissolved Na+ and Cl- ions. The water may be called a supernatant liquid. Super means "over", and natant is a variant of "natare", Latin for "to swim". Also recognize that water can be trapped in between the crystals on the bottom of the beaker. This liquid is interstitial, which means it is in narrow spaces between salt crystals. The same terminology is appropriate for water above centrifuged crystals.
How can sue make some pure dry copper chloride crystals fro the mixture in the beaker?
Sue can heat the mixture in the beaker to evaporate the water and leave only the pure dry copper chloride crystals behind. The crystals can then be filtered out and dried to remove any remaining water.
Which physical method can be used for obtaining a sample of salt from a small beaker of salt water?
One method to obtain salt from salt water is through evaporation. Simply heat the salt water in the small beaker until all the water evaporates, leaving behind the salt crystals. Another method is to use a filter paper or a sieve to separate the salt crystals from the remaining water in the beaker.
What is the solute in drink crystals?
The solute in drink crystals is usually sugar or artificial sweeteners. When the crystals are dissolved in water, the sugar or sweeteners disperse throughout the liquid to give the drink its sweetness.
What happened inside a beaker and on the bottom of the glass cover after you heated the water in the beaker?
Inside the beaker, the water absorbed heat energy, causing its temperature to rise and eventually boil. The steam formed from the boiling water then condensed on the cooler glass cover, forming water droplets on the bottom due to the temperature difference between the inside and outside surfaces.
A beaker contains table salt dissolved in water describe one method a student could use to separate salt?
The student can use the process of evaporation to separate salt from water. By heating the solution in the beaker, the water will evaporate, leaving salt crystals behind. These salt crystals can then be collected once all the water has evaporated.

Kate and Janie are about to pour water into a beaker when they notice the beaker has a crack at the bottom. What should the students do with the beaker?
The students should not use the beaker with the crack as it poses a risk of breaking further while pouring water, potentially causing injury. They should find a different beaker that is intact and safe to use for their experiment.

The student can retrieve the salt by evaporating the water. They can do this by heating the solution in the beaker until all the water evaporates, leaving behind the salt. The salt can then be scraped or collected from the bottom of the beaker.
