| How are Hydronium and Hydroxide ions formed? |
|
Definition
The hydroxide ion is formed when the oxygen atom in a water molecule takes an electron away from one of its hydrogen atoms so it becomes negatively charged.
The Hydronium ion is formed when the hydrogen atom in a water molecule loses its electron and becomes positively charged. |
