### Equilibrium sign

Do we add the equilibrium sign if we are writing the dissociation of a strong acid/strong base ?

No, because for strong acids and bases we assume 100% dissociation, so after the reaction there will be no reactants in solution, only products

No, since strong acids and bases are completely dissociated, it is only a one way reaction. Weak acids and bases use the equilibrium sign because the weak acid/base is not completely dissociated, so there are still H+ or OH- ions on the reactant side, as well as some on the products side.

No because reactions with strong acids and bases only go in one direction, while reactions with weak acids and bases reach equilibrium and then occur at a constant rate.

### Re: Equilibrium sign

Equilibrium sign is added only for weak acids and bases since they do not dissociate or ionize fully.
