Water dissolves some molecular compounds because water is a polar molecule.
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.
Sodium chloride is dissolved in water because is a polar, ionic compond.
Some molecules such as triglycerides, fatty acids, steroids, and cholesterol don't dissolve in water because of their molecular structure. They do, however, dissolve in fat. Any toxic chemical with this type of molecular structure would tend to dissolve in fat, not in water.
Ionization
An aqueous solution is one where water is the solvent. The nature of the solute is not relevant.
True
because it doesn't have enough molecular motion
Dissolve them in water. If the solution conducts electricity, then the solute is an ionic compound. If not, then it is a molecular compound.
No, all oils are water-repellents. Because of the molecular structure of oils, they are unable to bond to the water.
O is negative, H is positive. The charges pull things apart.
HCl lowers the boiling point of water more than HC2H3O2 does.
No mobile charged particles are present in sufficient concentration.
