Calculate the $$\mathrm{pH}$$ of $$1\mathrm{L}$$ of pure water at equilibrium. How will the $$\mathrm{pH}$$ change after $$0.008\mathrm{moles}$$ of the strong base sodium hydroxide $$(\mathrm{NaOH})$$ are dissolved in the water? Now, calculate the $$\mathrm{pH}$$ of a $$50\mathrm{mM}$$ aqueous solution of the weak acid 3 - $$(N$$-morpholino) propane-1-sulfonic acid (MOPS) in which 61 percent of the solute is in its weak acid form and 39 percent is in the form of MOPS's corresponding base (the pKa for MOPS is 7.20). What is the final $$\mathrm{pH}$$ after $$0.008$$ moles of NaOH are added to $$1\mathrm{L}$$ of this MOPS buffer?
