- Hydroxide (OH-) is a negatively charged ion consisting of one oxygen atom and one hydrogen atom. It is found in many compounds, including water (H2O), sodium hydroxide (NaOH), and potassium hydroxide (KOH). Hydroxide ions are also known as hydroxyl ions.
- Hydrogen (H) is a neutral atom with one proton and one electron. It is the most abundant element in the universe and is found in many compounds, including water (H2O), methane (CH4), and ammonia (NH3). Hydrogen gas (H2) is a colourless, odourless, and tasteless gas that is highly flammable.
So, while both hydroxide and hydrogen contain hydrogen atoms, they are different entities with different chemical properties.
