Acetic acid CH3COOH 1.8 × 10-5 Acetylsalicylic acid (aspirin) HC9H7O4 3.0 × 10-4 Equal volumes of 0.506 M aqueous solutions of acetic acid (CH3COOH(aq)) and sodium acetylsalicylate (NaC,H-04) 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 "CH3COOH" NOT "CzH;CO,H". It is not necessary to include...
