Solvent is, in simplest terms, something in which you dissolve another substance (also called as solute) and this mixture will yield what we know as a 'solution'.
Solvents are generally liquid (water is the most common example), but can also be gas or solid. Solutes are the materials that are dissolved into solvents and we end up with solution.
Some examples of solvents are water, ethanol, toluene, chloroform, acetone, milk, etc.
Examples of solutes include, sugar, salt, oxygen, etc.
There are numerous examples of solutions. For example milk (solvent) and sugar (solute) makes sweet milk. Air is made up of gases (oxygen, nitrogen, carbon dioxide, etc.). Alloys are made up of metals, for example, bronze is made up of copper and tin. River water contains water (solvent) and dissolved oxygen (solute).
You can find many other examples of solvent, solute and solution in all aspects of our lives.
A solution is the final product once a solute is dissolved within a solvent. A very important example of a solution used in hospitals is saline used in IVs. Saline is made up of salt and water. Salt is dissolved into the water, therefore salt is the solute and water is the solvent.
A solute is a substance that can be dissolved within another substance which is the solvent. The solute/solvent combination is a solution.
Solute = being dissolved
Solvent = does the dissolving
Solution = Solute + Solvent
Some common examples are:
Sugar + Water = Sugar Water
Salt + Water = Salt Water
Concentrated OJ + Water = Orange Juice
A solution is a mixture of two or more things. In a solution you have two parts the solute (what is being dissolved) and the solvent (what is doing the dissolving). Examples include:
Solution Solute Solvent
Kool-aid Kool-aid packet water
salt water salt water
chocolate milk chocolate syrup milk
water is known as the 'universal solvent' as many substances are able to dissolve in it.
