Bunda Cliffs is an aboriginal name used for the Nullarbor coastal cliffs. The sea cliffs, which are some 60 (200 ft) to 120 meters (400 ft) high, extend for around 100 km along the Great Australian Bight near its northern extremity and are close to the Nullarbor Plain in a very sparsely settled area of Australia.
H+ means the charge of the hydrogen ion. i.e when a hydrogen ion is formed, more oftan than not, an electron is lost from hydrogens outer sheel giving the ion a charge of +1. H+ ions are also basicaly the thing that makes an acid. e.g Hydrochloric acid (HCl) when in solution seperates into Cl- ions and H+ ions.
To be more precise, pH is the negative logarithm of the hydrogen ion concentration: pH = âlog [H+] The square brackets around the H+ automatically mean concentration to a chemist. What the equation means is just what we said before: for each 1-unit change in pH, the hydrogen ion concentration changes ten-fold.
