What else can I help you with?
Carrots in salt would it be hyptonic or hypertonic?
Carrots in salt would be hypertonic. This is because the salt concentration outside the carrot cells is higher than inside the cells, causing water to move out of the cells, leading to dehydration and shrinkage of the carrots.
Why did we use salt in the extraction solution?
Salt was used in the extraction solution to help separate the DNA from other cellular components by creating a high-salt environment that causes the DNA to clump together and precipitate out of the solution.
When salt is dissolved in water what is formed?
Salt water. When the salt dissolves, it is not a chemical reaction, so no new substance is created. The water molecules surrounded each ion in the solid NaCl separating the Na+ ions from the Cl- ions.
The contrast of solute and solvent?
A solute is the substance that is dissolved in a solution, while a solvent is the substance that does the dissolving. The solute is typically present in a smaller quantity compared to the solvent. For example, in a saltwater solution, salt is the solute and water is the solvent.
What type of solution will cause water to move into a cell?
The terms associated with this phenomenon can be quite difficult to get the grasp of for some reason or another to all students. The best way I can describe this is by starting with the solution. By definition of a solution you have a solute and a solvent. The solute is the substance with the lesser concentration. ( e.g. if you have a solution of Salt Water The NaCl (table salt) is dissolved into the H2O( water) since the Salt is being dissolved it is the solute. If you have 2 solutions of salt water Solution A : 10% salt; 90% Water Solution B : 30% salt and 70% water. The two solutions are obiviouslty not equal in proprtion (if they were they would be Isotonic [ equal concentration amounts of water in both solutions]) A Hypertonic Solution Means that it has a higher concentration of solute then the solution in comparison. in this case the solution B would be hypertonic to Solution A. This because the Solute concentration is higher in B than A. Solution B is the hypotonic to solution A because it has a lower concentration of solute. Osmosis is the diffusion of water across a membrane from an area of higher concentration to an area of lower concentration so since Solution B has a lower concentration of water Solution A will pass water into it going from hypotonic to hypertonic.
Does salt float?
no, salt is more dense than water. It can mix in with water also, creating a solution.
Can an egg float on salt water and why?
Yes, a raw egg will float if the salt concentration is high enough. This is possible because adding salt creates a solution with a greater density than water. As more salt is added, the density of the solution increases. At a certain point, the density of the solution becomes greater than the density of the raw egg, allowing the egg to float in the solution.*This experiment is a very good demonstration of the principle of buoyancy.
Does egg always float in salt water?
An egg will float in salt water depending on the amount of salt found in the water because this increases the density of the solution. The density of salt water should always be higher than the density of the egg in order for it to float.
How is salt important in making heavy objects float?
dissolved salt increases the density of solution than the density of heavy metal, which help the heavy substance to float
Why does an egg floats in salt solution but not in fresh water?
An egg floats in a salt solution because the density of the salt solution is higher than that of the egg, causing the egg to float. In fresh water, the density is lower than the egg, causing it to sink.
Does dissolved salt float in a cup of water?
No, salt dissolved in water does not float. When salt dissolves in water, it becomes dispersed throughout the liquid, increasing its density. This prevents the saltwater solution from floating in pure water.
What will happen to a wilt carrot if placed in salt water and return to find it fresh and firm?
The carrots were rehydrated in the solution.
What do you do to make an egg float?
You have to increase the specific gravity of the solution in which you are trying to float the egg. You do this by adding solutes to the solution. There is a very old cooks saying that brine (salt water) used for pickling should be "strong enough to float an egg".
Explain why an egg sinks in fresh water but floats in a strong solution of salt?
One substance will float on another if its density is less. By adding salt you are increasing the density of the solution. As you add salt, at some point the density of the solution will reach and then exceed the density of the egg
Why does salt float?
Salt is soluble in water, doesn't float.
Do salt and sugar and flour make a egg float?
No, salt, sugar, and flour alone will not make an egg float. The density of an egg is higher than that of salt, sugar, and flour, so the egg will sink in these substances. However, if you were to dissolve a large amount of salt or sugar in water to create a solution with a higher density than the egg, then the egg could float in that solution.
Will a boiled egg float if you add salt to water?
Yes, it will eventually. When you add salt to water, you are increasing the density of the solution, but not the volume, because the salt dissolves (dissociates). Since density is mass divided by volume, there is a direct relationship between the solution's mass and its density. They increase together even as the volume remains constant. An egg will float in a salt solultion if the molarity is about 2.5 or above.
