The amino acid glycine is often used as the main ingredient of a buffer in biochemical experiments. the amino group of glycine, which has a pka of 9.6, can exist either in the protonated form (—nh1 3) or as the free base (—nh2), because of the reversible equilibrium ronh1 3 δ ronh2 1 h1 (a) in what ph range can glycine be used as an effective buffer due to its amino group? (b) in a 0.1 m solution of glycine at ph 9.0, what fraction of glycine has its amino group in the —nh1 3 form? (c) how much 5 m koh must be added to 1.0 l of 0.1 m glycine at ph 9.0 to bring its ph to exactly 10.0? (d) when 99% of the glycine is in its —nh1 3 form, what is the numerical relation between the ph of the solution and the pka of the amino group?
