WebJan 16, 2024 · The pH is about 12.7. Explanation: NaOH is a strong base, meaning it will dissociate basically completely in solution to form [Math Processing Error] and [Math Processing Error] ions in solution. One mole of [Math Processing Error] ions is created for every mole of NaOH that is dissolved. WebThe concentration of the ionized water is less. than one-millionth molar at room temperature. We can write the autoionization of water as a. dissociation reaction similar to those previously. done in this chapter. Because the activity of pure water is 1, the. equilibrium constant for this reaction is. KcH3OOH-.
