Detailed explanation-1: -Water molecules have a polar arrangement of 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.
Detailed explanation-2: -Water, which not only dissolves many compounds but also dissolves more substances than any other liquid, is considered the universal solvent. A polar molecule with partially-positive and negative charges, it readily dissolves ions and polar molecules.
Detailed explanation-3: -What properties does water have that make it a very versatile fluid? High heat capacity, heat of vaporization, polar solvent properties, reactivity, and cushioning.
Detailed explanation-4: -Water’s polarity allows it to form covalent bonds with many substances. Natural water has a pH of approximately 5.6, which is slightly acidic. Acids can dissolve more substances than bases can. Because it is polar, water forms ionic bonds with the ions in substances such as NaCl (salt).
