What is dissociation reaction?

Answer:  A dissociation reaction is a chemical reaction where a compound breaks into two or more components. 

The formula for the dissociation reaction is: AB      A + B

These reactions are generally reversible chemical reactions. One of the ways to find a dissociation reaction is when there is only one reactant but multiple outputs.

Example of dissociation reaction: H₂O → H+ + OH-

When acids undergo dissociation reactions, they produce hydrogen ions. Such as: HCl → H+(aq) + Cl-(aq)
