As you saw in the video, the ph of a 0.1 m solution of acetic acid, hc2h3 02, (ka 1.8 x 10^-5) is 2.9. based on this observation, which statement below best describes the ph of a 0.1 m solution of lactic acid, hc3h o3, (ka e 1.4 x 10^-4)?
a) since lactic acid has a larger acid dissociation constant than acetic acid, a 0.1 m solution of lactic acid will have a larger ph value than a 0.1 macetic acid solution.
b) the ph of a 0.1 m acetic acid solution will be equal to the ph of a 0.1 m lactic acid solution since both are weak acids.
c) since lactic acid has a larger acid dissociation constant than acetic acid, a 0.1 m solution of lactic acid will have a smaller ph value than a 0.1 m acetic acid solution.
d) since lactic acid has a smaller acid dissociation constant than acetic acid, a 0.1 m solution of lactic acid will have a larger ph value than a 0.1 m acetic acid solution.
