The correct statement about OH ions :
It’s a polyatomic anion because it has more than one atom and a negative charge.
<h3>Further explanation
</h3>
Ions are atoms that have a charge
Ions are formed because capturing or releasing electrons.
Ions can be differentiated based on the number of constituent elements they become
- 1. monatomic ion, if it comes from one element, such as K⁺, Mg²⁺, Cl⁻
- 2. polyatomic ion, if it comes from two or more elements such as PO₄³⁻, SO₄²⁻, ClO₃⁻
Based on the charge, ions can be divided into:
happens if the atom releases electrons, for example
Al³⁺, ---> Al⇒ Al³⁺ + 3e⁻
Pb²⁺, ----> Pb⇒ Pb²⁺ + 2e-
happens if the atom captures electrons, like
S²⁻, S + 2e⁻⇒ S²⁻
F⁻, F + e⁻⇒ F⁻
OH- ions are usually associated with bases
According to Arrhenius, defines that
A base is a compound that can release OH- ions
Example:
NaOH (aq) -> Na + (aq) + OH- (aq)
The amount of OH- ions that can be produced by base compounds is called base valence.
OH ions are formed from the elements O and H so that they are polyatomic ions
OH ions are negatively charged so they are called anions
