When a substance is unable to dissolve into a solvent, it will remain as a separate phase or form a suspension or precipitate. In other words, it will either float or sink in the solvent, or it will form small solid particles that do not dissolve. Examples include oil and water, where oil does not dissolve into water but forms separate droplets or layers.
Some substance cant dissolve in water because they do not create hydrogen bonds with water molecules. It is very important for the substance to make hydrogen bondis with water molecules in order to dissolve. e.g. gasoline wont dissolve in water because it doesn't have a highly electronegative atom to react with posively charged hydrogen of water molecule. The polarity of the water molecule allows it to dissolve certain substances easily but not others which resist the "efforts" of water molecules to "wedge" themselves between the substance's molecules.
osmotically active
The cell would be unable to maintain a stable internal environment.
it starts to germinate but is either unable to grow and reach the female gameta or is unable to fertilize it
no
There are plenty of metals that will dissolve given the correct solvent or solvents combined. Google "royal water"
the solute becomes so tiny we are unable to see them with our naked eyes
Materials like salt and sugar will dissolve in the water and are called soluble as they dissolve completely in the water, where as substances that do not dissolve in water like sand are called insoluble materials.
Water is known as the universal solvent. More substances can be dissolved in water than any other chemical.This is due to the polarity of the water molecule. Water is made of hydrogen, which carries a slight positive charge, and oxygen, which carries a slightly negative charge. This means that whatever the charge of the substance either the hydrogen or the oxygen will be attracted to it. Although water will dissolve most substances, there are some that is will not dissolve because they have a stronger charge than the water and the water is unable to break them apart.
When a solution is saturated that indicates that solution is at a maximum concentration. The solvent is unable to dissolve more of the solute. If more of the solute it placed in the solution, it will not dissolve, yet rather sit at the bottom as a crystallised form. The temperature can also affect the capacity of the solvent's abilities to dissolve the solute eg. it is easier to dissolve sugar into a drink if it is hot than when it is cold. Sometimes if the drink cools down, the crystals settle at the bottom. -- Neenish Tart
I'm not sure what your asking but the term for substances that are unable to dissolve in water are called unsoluable.
Due to the density of the oil it is unable to dissolve a lolly
Commonly describes as the "versatile solvent", water is a substance that can dissolve almost anything. Because of this, water in nature and in use is rarely pure, and may have some properties different from those in the laboratory. Salts such as sodium chloride dissolve in water by dissociating as each ion becomes surrounded (spherical shape) by the polar water molecules. This sphere of water molecules around each dissolved ion is called a hydration shell. Shielded by this shell of water molecules, the ions remain in solution because they are no longer affected by attractive forces from surrounding ions.
In order for a substance to be a primary standard it must be able to dissolve in water. Since iodine is unable to do this it cannot be used as a primary standard
naphthalene is only made of two types of atom: carbon and hydrogen. There is little difference in electronegativity between these atoms (how well they can pull on electrons) so there is an equal distribution of electron density across the molecule, thus being NON-POLAR. Water on the other hand is comprised of oxygen and hydrogen atoms, between which there is a large difference in electronegativity. This means that there is an imbalance of charge across the molecule resulting in water being POLAR. a polar molecule is unable to interact with a non-polar molecule as they don't 'have anything in common' in terms of their charge distribution. Naphthalene will dissolve in petrol due to petrol being a non-polar solvent.
Solutions form when the solute particles dissolve into the solvent particles. Then the solute particles go in between the solvent's particles and the solute's particles to therefore make a solution. The polarity of the water molecules (slightly negative around the oxygen atom, slightly positive on the hydrogen side) helps dissociate the weak bonds of the solute. The ions formed then flit about in the water, unable to reconnect with their original counterparts for any significant time (not enough to form a solid and drop out, called a precipitate). A solution is a substance dissolved in water or other solvents.
Any substance which is unable to form water as a product of a neutralization reaction is not an acid.
