###### FREE Expert Solution

A) Since NaOH is a strong base, it will dissociate completely in the solution. This means that the concentration of hydroxide ions after dissociation will be the same as the initial concentration of NaOH. [H3O+] can be calculated using the ion-product constant of water (kw) and [OH- ###### Problem Details
