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.
Why is paraffin oil constantly stirred to determine the melting point of benzene acid?
Paraffin oil is used for determination of boiling point and melting point for the following reasons: It has a very high boiling point and so it can be used to maintain high temperatures in the boiling and melting point apparatus without loss of the substance.
