Does forming OH- ions in water base solution absorb energy

AI Thread Summary
Forming OH- ions in a water base solution involves energy changes that can be either endothermic or exothermic, depending on the specific base used. The mechanism typically involves base dissociation, which can lead to the formation of unstable ions from stable molecules. While many bases release energy during dissociation, some, like ammonia in water, may absorb energy, making the reaction endothermic. Calculating the energy balance for these reactions requires careful consideration of the specific base and its properties. Reliable resources for further understanding include chemistry textbooks and academic articles focused on thermodynamics and ion formation.

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?

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?

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!
