Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid.

This is important to every living thing on earth. It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
It is water's chemical composition and physical attributes that make it such an excellent solvent.
Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. This allows the water molecule to become attracted to many other different types of molecules. Water can become so heavily attracted to a different molecule, like salt (NaCl), that it can disrupt the attractive forces that hold the sodium and chloride in the salt molecule together and, thus, dissolve it.

FAQs - You will find the answers to all the questions below in this article.
Why does water dissolve?
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen. In a covalent bond electrons are shared between atoms. ... It is this polar property that allows water to separate polar solute molecules and explains why water can dissolve so many substances.
What makes things dissolve better in a liquid?
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
How easily something dissolves in water or another liquid?
solubility Add to list Share. Use the noun solubility to refer to how easily something dissolves in water or another liquid. Salt has high solubility, easily dissolving in water, while oil has low solubility in water, and sand is not at all soluble in water.
What substance dissolves most?
Water, which not only dissolves many compounds but also dissolves more substances than any other liquid, is considered the universal solvent.
Why do things dissolve?
Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. ... They do this by pulling away the ions and then surrounding the salt molecules.
What dissolves easily in water?
Stone, iron, pots, pans, plates, sugar, salt, and coffee beans all dissolve in water. ... Substances which dissolve easily and readily in water (sugar, salt, etc.) are called water-loving, or hydrophilic substances. On the other hand, some solutes are non-polar and do not have any positive or negative charges.
Why do water molecules have high cohesion?
Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another. ... Thus, the water molecules at the surface form stronger interactions with the neighbors they do have.
Why do substances dissolve faster in hot water?
When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
Does adding more solvent increase solubility?
Increasing the surface area increases the rate of solubility of a solid because a larger number of molecules have contact with the solvent.
How are substances dissolved?
In order for a substance to dissolve, the molecules of the solute need to interact with the molecules of the solvent. ... The oppositely charged ends of polar water molecules attract the ions and pull them away, resulting in dissolving.
Good Luck!
