How do hydrogen ions exist in water??? |
| Answer» \tThe hydroxide concentration is a direct measure of a solution\'s pH. This may be formed in water/pure water where an acid exist. H3O+ is its chemical formula By combining an\xa0H+ion with an H2O molecule,\xa0it is formed too.\tThe H+ion has a trigonal pyramidal geometry\xa0and comprises 1 oxygen atom and 3 hydrogen atoms. There is a single pair of electrons in oxygen that gives it this shape. Between the atoms, the bond angle is around 113 degree. ---- H2O(l)⇌OH−(aq)+H+(aq\tAs H+ions are formed, they bond with H2O molecules\xa0in the solution to form H3O+(the hydronium-ion). This is due to the hydrogen ions that is not present in aqueous solutions, however takes the form of water H2O | |
