The OH^- anion is referred to as hydoxyl, hydroxide, hydroxy, etc.
The cation would be C6H5NH3+ and the anion would be C6H5NH-
If you think to anion OH- - the answer is no.
'OH^-' ions are named as 'Hydroxides'. e.g. Potassium hydroxide KOH. Calcium hydroxide 'Ca(OH)2'. NB The hydroxide ion is ALWAYS written as 'OH'. Never' 'HO'. NNB Being a negatively charged ion it correctly named as an 'ANION'.
Acids in their pure state are named based on the anion they contain. For example, hydrochloric acid contains the chloride anion, so it is named hydrochloric acid. Sulfuric acid contains the sulfate anion, so it is named sulfuric acid.
In NH4OH, the anion is the hydroxide ion (OH⁻). Ammonium hydroxide is a solution of ammonia (NH3) in water, and in this context, it dissociates into ammonium ions (NH4⁺) and hydroxide ions (OH⁻) when dissolved. Therefore, the anion present in ammonium hydroxide is OH⁻.
An anion is named using the base element with an -ide suffix. Ex: Br- (Bromine anion) is named bromide sulfur- sulfide, ect.
The hydroxyl anion - (OH)-.
Examples: hydroxyl radical (OH.) and the superoxide anion O2(-).
An antimoniate is an anion of pentavalent antimony, Sb(OH)4- or any salt containing this anion.
The hydroxide of lead is Pb(OH)2; Pb(OH)+ is only an anion in alkaline solutions.
The chemical name for an ionic compound with a polyatomic cation and polyatomic anion would typically be named using the names of the individual ions. The cation would be named first followed by the anion, with the ending of the anion typically changed to "-ide," similar to naming binary ionic compounds.
Barium hydroxide is not a cation or an anion. It is a compound. It is made of barium ions and hydroxide ions.
