GENERAL HISTOLOGY

Detailed explanation-1: -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).

Detailed explanation-2: -The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).

Detailed explanation-3: -As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids.
