The substance that dissolves is the solute (SAHL-yoot).
When a substance dissolves in another substance, it is called soluble.
Therefore a solute is soluble in a solvent.
Water functions as a solvent in some foods.
Because it is a polar molecule, water can dissolve ionic substances.
This happens because the charged ends of the water molecule attract ions of the opposite charge, pulling them out of their crystal structure into solution.
For example , sodium chloride (table salt) dissolves in water because the negative oxygen end of the water molecule attracts the positive sodium ion.
The positive hydrogen ends of the water molecule attract negative chloride ions.
In addition , since water is molecular, it can dissolve many molecular substances, such as sugar, soluble vitamins and minerals, and flavorings.
The flavorings in tea leaves or coffee beans dissolve in water to form popular beverages.
Sugar added to sweeten strawberries dissolves in the berries’ free water to form a sweet syrup.
Vitamin C can dissolve into cooking water and be lost during food preparation.
You will learn more about solutions in Chapter 13.
