Does forming OH- ions in water base solution absorb energy

[sr241]

does forming OH- ions in water base solution absorb energy ?
How this mechanism works, from stable molecules to unstable ions?
is this reaction endothermic or exothermic?

 

[Borek]

Forming by what? Water autodissociation? Base dissociation? These don't have to be identical.

does forming OH- ions in water base solution by "base dissociation" absorb energy?

How this mechanism works, from stable molecules to unstable ions?
is this reaction endothermic or exothermic?

 

[Borek]

is this reaction endothermic or exothermic?

I don't think there is a single "one size fits all" answer. Most likely it depends on the base. I guess in most cases it is probably exothermic.

in case of ammonia water solution is it endothermic? how to calculate energy balance for it?

share me any reliable resources or books for calculating!
