Water is known as the universal solvent because more solutes dissolve in it than any other substance. A solvent is a substance, usually a liquid, that dissolves other substances to form a solution.Continue Reading
According to About, water's ability to dissolve a variety of substances stems from the polarity of its hydrogen molecules. Due to its polar nature, water easily dissolves substances that are polar or ionic.
The water molecule carries electric charges that are slightly positive on the hydrogen side and slightly negative on the oxygen side. As such, ionic compounds easily dissociate in water into positive and negative ions.
The positive ion of the compound attracts the oxygen side of the water molecule while the negative ion attracts the hydrogen side. This unique structure of the water molecule results in the relatively unusual behavior of water, such as its increase in density at lower temperatures.
Despite water being dubbed the universal solvent, there are many substances that do not properly dissolve in water. Solubility decreases if the attraction between opposite-charged molecules in a compound is high. For instance, most hydroxides exhibit low solubility in water. In addition, many organic compounds do not dissolve in water, including waxes and fats.Learn more about Chemistry
When discussing solutions, the solute is the substance which dissolves, while the solvent is the substance into which the solute dissolves. Creating a salt water solution involves dissolving salt in water, making salt the solute and water the solvent. However, determining which is the solute or solvent is not always so simple, and some rules exist for determining which substance dissolves in the other.Full Answer >
Soluble substances are those that easily dissolve in a solvent, such as water, and include sugar, salt, alcohol and some dishwashing detergents. In chemistry, solubility of a substance is a quantitative term that refers to the amount of substance that can dissolve in a given volume of a solvent. A substance is considered soluble if more than 0.1 gram of that substance can dissolve in 100 ml of solvent.Full Answer >
In chemistry, the term "hydrate" refers to a substance that contains water, while an anhydrous substance contains no water. Hydrates and anhydrates differ greatly in their reactions to water and their common uses.Full Answer >
There is a direct relationship between absorbance and concentration is the higher the absorbance of a substance, the more concentrated its solution will be in water or another medium. In chemistry, this is a principle known as the Beer-Lambert Law.Full Answer >
