Consider the titration of 100.0 mL of 0.100 M HNO3 by 0.200 M NaOH.Calculate the pH after 34.5 mL of NaOH has been added.At what volume (in mL) of NaOH added does the pH of the resulting solution equal 7.00.
What is the strongest base that may exist in water? What happens to stronger bases? (Use methoxide, CH3O1-, as an example.)
Draw a titration curve for both of these peptides. Be sure to label the axes properly, indicate the pKa values, the equivalence points and the buffering regions
