Salt dissolve in water. That doesn't mean that a chemical change has
taken place however. A chemical change is where bonds are broken and NEW
BONDS FORM causing a rearrangement of atoms into new molecules. Dissolving
is a physical process where the substance retains its own physical
characteristics but just changes state or shape etc. When salt is put in
water, the sodium and chloride atoms are pulled apart by the water. They
disappear. But if the water is taken away, the sodium and chloride atoms
rejoin with each other.
Yes, water can dissolve salt. When salt is mixed with water, the water molecules surround the salt ions and break them apart, allowing the salt to dissolve into the water.
Because salt water is denser. If you pour salt water and fresh water [one with food coloring] into a glass, the salt water will sink below the fresh water. You are only a bit denser than salt water.
it is easier to float, salt water has a higher density. The more salt, the easier it is to float.
Objects float more in salt water compared to fresh water because salt water is denser. The increased density of salt water provides greater buoyancy for objects, allowing them to float more easily than in fresh water.
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.

Salt in water is an example of solubility.
You reach the solubility of salt in water when the salt stops dissolving and settles at the bottom, no matter how hard you try to mix it. You can increase solubility by increasing the water temperature.
In presence of salt the crystals grow faster because the solubility of salt decreases the solubility of any other compound in water.
Adding water to salt, is not increasing solubility, it is increasing the ammount of solvent, and thereby increasing the ammount of salt in solution :).
The solubility of salt in water increases with higher temperatures.
Salt dissolves more easily than sugar, in my experience. But the solubility is similar. :)
The volume solution in conical flask is very important in solubility ionic salt water. This is because it determines its solubility.
Solubilization of salt in water is a physical change.
Ammonium chloride has the greatest solubility in water at 25 degrees Celsius, with a solubility of 37.2g/100mL of water.
Yes, salt (sodium chloride) is soluble in ethanol and will dissolve to form a solution. However, the solubility of salt in ethanol is lower compared to its solubility in water.
Some examples of substances with high solubility are salt in water, sugar in water, and ethanol in water. Conversely, substances with low solubility include oil in water and carbon dioxide in water. The solubility of a substance depends on its chemical structure and the solvent it is placed in.
