WebHere, red dots signify hydrogen ions (H+) and blue dots signify hydroxyl ions (OH). Also shown are the approximate pH values for some common solutions. This pH scale ranges from 0 (most acidic) to 14 (most basic). A change of one unit on the scale corresponds to a tenfold change in the amount of H+ ions. WebA hydrogen bond is a weaker form of the bond than the covalent bond formed by the hydrogen atom and another element. A hydrogen bond is comparatively stronger than a simple dipole-to-dipole bond but weaker than an ionic bond. Hydrogen bonding occurs due to the attraction of two or more electrically charged molecules, which have a small …
