Equal volumes of 0.298 M aqueous solutions of acetylsalicylic acid (aspirin) (HC9H7O4(aq)) and sodium benzoate (NaC6H5COO)...
Equal volumes of 0.298 M aqueous solutions of acetylsalicylic acid (aspirin) (HC9H7O4(aq)) and sodium benzoate (NaC6H5COO) are mixed.
(1) Write the net ionic equation for the overall reaction that takes place as the system comes to equilibrium. Write acetic acid, benzoic acid or formic acid and their conjugates in the form RCOOH / RCOO-. For example, benzoic acid should be written "C6H5COOH" NOT "C6H5CO2H". It is not necessary to include states such as (aq).
(2) What is the value of the equilibrium constant for this reaction?
(3) What is the pH of the resulting solution?

Acetylsalicylic acid, also known as Aspirin, has a formula of
C9H8O4 and is a weak acid with a Ka of 3.0 x 10-4. It has been
suggested that a regular low-dose regimen of “baby aspirin”,
approximately 81 mg, may help reduce the risk of a heart
attack.
a. Determine the molarity of acetylsalicylic acid in a solution
of “baby aspirin” if a tablet containing 81.0 mg of acetylsalicylic
acid is dissolved in a cup of water (8.0 fluid ounces). Note:...
