Answer:
We call water a universal solvent because it can dissolve many different substances.
Explanation:
- Water is crucial to every living entity on earth. It is called the Elixir of life.
- Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid.
- Water acts as a solvent due to the polarity of each water molecule. Water molecules have a polar arrangement of oxygen and hydrogen atoms i.e. one side (hydrogen)of each water (H₂O) has a slight positive electrical charge and the other side (oxygen) had a slight negative charge.
- This allows the water molecule to become attracted to many other different types of molecules.
- This lets water dissociate ionic compounds into their positive and negative ions.
- The positive part of an ionic compound is attracted to the oxygen side of the water while the negative portion of the compound is attracted to the hydrogen side of the water.
