Hydroxide ion

Hydroxide Ion is a water-derived anion composed of an oxygen atom and a hydrogen atom. It's a vital part of acid-base reactions, neutralization reactions, and solubility equilibrium.

Overview[edit | edit source]

The hydroxide ion forms a type of ionic bond with a cation to create a compound. This compound is often a base, as the hydroxide ion is capable of accepting a proton from an acid during a reaction.

Properties[edit | edit source]

The hydroxide ion carries a negative charge, which allows it to bond with positively charged ions. It is also a strong base, meaning it readily accepts protons from acids.

Role in Acid-Base Reactions[edit | edit source]

In acid-base reactions, the hydroxide ion acts as a base, accepting a proton from the acid. This results in the formation of water and a salt, effectively neutralizing the acid.

Role in Solubility Equilibrium[edit | edit source]

In solubility equilibrium, the hydroxide ion plays a crucial role in determining the solubility of certain compounds. The presence of hydroxide ions can increase the solubility of some substances, while decreasing the solubility of others.

Safety[edit | edit source]

Due to its strong basic nature, the hydroxide ion can be harmful if it comes into contact with skin or eyes, or if it is ingested. It is important to handle substances containing hydroxide ions with care.
