wants to make a 1 liter solution of 0.5 M alanine at pH 2.6. The pKa of carboxylic acid is 2.34 and the pKa of α-amino group is 9.60. Use this information to answer questions 1-4. Which groups would be fully protonated or fully deprotonated at this pH?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
