Does forming OH- ions in water base solution absorb energy

In summary, the formation of OH- ions in a water base solution can either be endothermic or exothermic, depending on the specific base used. The mechanism for this process involves the conversion of stable molecules to unstable ions. Calculating the energy balance for this reaction may vary depending on the specific base and can be found in reliable resources or books on the subject.

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?

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!
 

1. What is the process of forming OH- ions in a water base solution?

The process of forming OH- ions in a water base solution is called ionization. This occurs when a substance, such as a base, dissolves in water and releases OH- ions into the solution.

2. How does the formation of OH- ions in water base solution affect the pH?

The formation of OH- ions in a water base solution increases the concentration of hydroxide ions, which in turn increases the pH of the solution. This makes the solution more basic.

3. Does the formation of OH- ions in a water base solution absorb or release energy?

The process of ionization, which forms OH- ions in a water base solution, typically releases energy. This is because the interactions between the solute particles and the water molecules are exothermic.

4. Can the formation of OH- ions in water base solution be reversed?

Yes, the formation of OH- ions in a water base solution can be reversed through a process called neutralization. This occurs when an acid is added to the solution, which neutralizes the OH- ions and brings the pH back to a neutral level.

5. How does the formation of OH- ions in water base solution relate to the strength of the base?

The strength of a base refers to its ability to fully dissociate in water and release OH- ions. Therefore, the more OH- ions that are formed in a water base solution, the stronger the base is considered to be.
