Explain why equilibrium calculations are not necessary to determine ionic concentrations of certain strong electrolytes such as NaOH and HCl. Under what conditions are equilibrium calculations necessary as part of the determination of the concentrations of all ions of some other strong electrolytes in solution?
Equilibrium concentrations are not important to determine ionic concentrationsin the solutions of a strong acid and a strong base. We need the equilibriumconcentrations to determine the ionic concentrations in weak acid and weakbase solution.

problem. What has happened from Chapter 14 is asking us to explain why it delivering calculations are not necessary to determine ionic concentrations of strong acids and bases such as sodium hydroxide and hydrochloric acid. And if that's the case, then when do we need to consider equilibrium? Cock calculations, um, to determine ionic concentrations. So, um, strong acids and bases such as hydrochloric acid when they react with water, disassociate completely. And that is why we do not need to consider equilibrium calculations. So that's supposed to be two. So when they react with water, they're going to associate completely, which is why we do not need to consider equilibrium. Calculations, however, for strong excuse me for weak acids and week basis, they do not associate completely. So that is why we need must consider thank you equilibrium calculations because they do not associate completely. And the rate of Ford reaction on the backwards reaction are equal, meaning that the formation of convict base is equal to the formation of the asset. Wants us right out the rest of this equation so we can see that, um, strong. Excuse me. Weak acids do not dissociate completely area. So this reaction is constantly in flux, these molecules losing its proton, but it's also gaining it back. Um, and that is why we have to.
