because the interparticle spaces were filled by salt
The solubility of a substance in water is usually determined by the polarity of the substance and water molecules. Polar substances tend to dissolve in water because they can form favorable interactions with water molecules. Nonpolar substances, on the other hand, are less soluble in water because they cannot form strong interactions with water. Temperature, pressure, and presence of other solutes can also affect solubility.
Oil and water do not mix because the triglyceride bonds have a hydrophobic (meaning does not like water) ends and therefore it will not react (or mix) with water. Water and oil don't mix because water is a polar substance and oil is nonpolar. Polar substances will only dissolve other polar substances or ionic substances, but will not dissolve nonpolar substances. Remember "Like dissolves like."
When paraffin is poured into water, it will float because paraffin is less dense than water. This is because paraffin is a type of hydrocarbon that is nonpolar and does not mix with water, which is a polar molecule. The two substances will not dissolve or mix together.
30% or less of our water is a fresh water
Substances that are less dense than water, such as oil, will naturally separate and float on top of water due to differences in density. Other substances like salt or sugar can dissolve in water and form a homogeneous mixture rather than separate out.
Water isn't always a solvent because not all substances can dissolve in water. Water can dissolve many substances due to its polarity and ability to form hydrogen bonds, but substances that are non-polar or have larger molecules may not be able to dissolve in water.
I would think it would dissolve faster in fresh water, as the fresh water doesn't have anything dissolved in it yet whereas the salt water has dissolved salts and so less room for the sugar molecules. A. yes; sugar does dissolve faster than salt does, in fresh water.
the substance can disslove in water (h2o) are most POWDER. Additional answer A powder is no more or no less able to dissolve in water than if that substance were NOT a powder. Powdering something does not help to make it soluble, though it might make it dissolve more quickly if it's able to dissolve at all. Some substances that dissolve to some extent are salt, sugar, calciul sulphate, copper chloride - millions of things
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
Nonpolar substances that repel water molecules.
Not all ionic salts dissolve in water, just most of them. Anyways, most molecular substances don't dissolve in water because they are more stable not dissolved. This is partly due to the fact that covalent bonds are stronger than ionic bonds. An example of a non-polar substances that can dissolve in water is diatomic fluorine, which when bubbled into water will dissolve.
I think its because its less dense but im not sure

No, not all substances dissolve in water to form a solution. Cooking oil is a good example, if you mix with water it will remain separated and float to the top - it is less dense. Water would have to break almost all its intermolecular hydrogen bonds in order to accomodate it (which of course it doesn't), and therefore it does not form a solution. Solubility depends on what you are adding to the water. If you are adding an alcohol for example, it has O-H bonds which will readily form hydrogen bonds with the water molecules, and so dissolves. Water is also a polar solvent, so ionic substances will also tend to dissolve in it. Hope that helps!
