what is a hydration number
Hydration refers to the interaction of a molecule or substance with water. Water interacts with several substances to form different products. The polarity of hydrogen and oxygen atoms in a water molecule is oriented with the reacting molecule accordingly. For example, sodium chloride reacts with water where oxygen surrounds the sodium ions and hydrogen reacts with the chloride ions. This type of electrostatic attraction allows the interaction of water with other compounds.
