A typical aspirin tablet contains 324 mg of acetylsalicylic acid (C9H8O4), a monoprotic acid having a Ka = 3.0 x 10-4. If you dissolve two aspirin tablets in 300. mL of water, what is the pH of the solution acetylsalicylic acid? A typical aspirin tablet contains 324 mg of acetylsalicylic acid (C9H8O4), a monoprotic acid having a Ka = 3.0 x 10-4.

Aspirin is acetylsalicylic
acid (ASA) (
C9H8O4). It reacts with NaOH ( a
base) to produce salt (sodium acetylate) and water. Both Aspirin
and NaOH react in 1:1 molar ratio, as
C9H8O4
+
NaOH →
NaC9H7O4
+ H2O
So, moles of NaOH = moles of ASA
Or, mmol of of NaOH = mmole of
ASA
; mmol is milli mol
and mmole of NaOH = Molarity of NaOH * Volume
of naOH used (in ml)
=
(0.1177 M) *...

Pre-lab Questions:
Importance A one-step preparation of aspirin from its precursor, salicylic acid, via an ester formation illustrates one of synthetic organic chemistry's most important uses, making the drugs that treat all types of illnesses. OH HOOH Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the ancient Greeks as a treatment for pain...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
