5 and 6

a 3.UU of a 5.UU the pH of (c) 2.00 3.401 (4) what's 12.00 pKa (a) 2.30 (b) H204H405: (5) which is a weaker acid (a) malic acid I (b acetic acid l HC2H3O2 pKa 4.74 (c) carbonic acid [Hoco pKa 6.37 (d) pyruvic acid I 3 pKa 2.50 3 3 which substance would be suitable to prepare a buffer at pH 7.00 malic pKA 3.401 aceptic acid LHC2Hao pKA 4.74 6.37 carbonic acid IH CO pK 2.50 p K. r mesak besse is oors sa ionized in o o 75 M solution then the a 12.88 Cd) 9-75 9.00 then the PK (d) 16.8 B. gave a pH OO then Yves

Explanation / Answer

(5) The higher the pKa, the weaker the acid. Therefore, the order of acidity is :

(weakest acid) Carbonic Acid < Acetic Acid < Malic Acid < Pyruvic Acid (strongest acid)

(6) Carbonic Acid
