A 0.5130 g aspirin tablet which was dissolved in 95 percent ethanol required 27.98 mL of 0.1000 M NaOH for neutralization Then an additional 42.78 mL of 0.1000 M NaOH was added and the soln was heated?

okay so I'm continuing the question since there wasn't any more space allowed:
...to hydrolyze the acetylsalicylic acid. After the reaction mixture was cooled, the excess base was back-titrated with 14.29 mL of 0.1056 M HCl. how many grams of acetylsalicylic acid are in the tablet? What % w/w of the tablet is acetylsalicylic acid?
-----------
I suppose that the tablet of aspirin have 0,5041 g acetylsalicylic acid or 98,26 %.
The question is surprisingly long, with exagerate data, after my opinion.

What color does blue litmus paper turn when dipped in aspirin?
Aspirin is a low soluble acidic substance, so only WHEN (finally) dissolved in water, it will turn blue litmus into red. Aspirin = 2-acetoxybenzoic acid = acetylsalicylic acid = C9H8O4 = (CH3COO)-C6H4-(COOH)
What liquid dissolves aspirin the fastest tonic water or distilled water?
I did this experiment for my science class and i got they both dissolved at the same time
An experiment was performed in lab that was supposed to produce aspirin. How could chromatography be used to tell if aspirin was actually the product of the reaction?
i would recommend using high performance liquid chromatography or the common thin layer chromatography using a spot of the sample and a spot of dissolved aspirin to compare the Rf-value or relative retention times of the 2 spots to determine if you have aspirin
Is dissolved aspirin reversible?
No. Aspirin prevents the synthesis of Thromboxane A2 which induces platelet aggregation (formation of a clot) and platelet release reaction. Aspirin inhibits this platelet aggregation for the life of the platelets, which is between 7-10 days. The cool thing with aspirin is that it thins your blood, the bad thing is that it thins your blood and if you want to stop taking aspirin (for any reason, even before surgery) you have a 3x increase of stroke or heart attack for 8-10 days because of its rebound effect. Aspirin is a light-weight compared to Heparin or Coumadin, but Heparin is easily reversed with Protamine-sulfate solution 1% and Coumadin with Vitamin K - something to think about. Maybe one day a drug will be created to reactivate Thromboxane A2 synthesis, but not yet. Trust your PA-C's.
What is the difference between aspirin to buffered aspirin?
Buffered aspirin has an added buffering agent so that it is easier on the stomach.
How does aspirin effect roses?
Aspirin can be dissolved in a vase of water to help prolong the life of the flowers. The aspirin gives them extra nutrients and is usually what is the basis of the packets florists give customers.
What pH would you expect aspirin dissolved in water to exhibit?
Aspirin is acetylsalicylic acid. From the name you should expect a pH of less than 7. Exactly how much less depends on how much aspirin and how much water.

Why do Aspirin Tablets dissolve faster in hot water?
asprin tablets dissolve quicker in hot water because the particles inside the tablet are more affected by hot water
Does baby aspirin given to a cat go by weight?
It is not advisable to use human drugs to treat animals unless recommended by your vet. Do not give aspirin to your cat as cats do not have the required enzymes to break it down. Aspirin is highly toxic to cats and can be fatal if administered.
Can you take aspirin and amoxicillin together?
Yes, if both drugs are required for you. There is no significant interaction between Amoxil and Aspirin.
What does Alka-Seltzer do to soda?
Alka-Seltzer: aspirin + citric acid + sodium hydrogen carbonate (NaHCO3) Soda: carbonated water (carbon dioxide dissolved in water)
What is the pH balance of dissolved aspirin?
there is no logical reason to believe that "acetylsalicyclic acid" would have a pH of 15...this would be a base.
What preparations are required with plastic surgery?
Preparation for nonemergency plastic or reconstructive surgery includes individual education.medical considerations.avoid using aspirin or medications containing aspirin for a week to two weeks before surgery.
Does the aspirin dissolve faster than sugar in a glass of water?
Aspirin is an acid. In solution in water, it breaks down into cations and anions and is thereby able to take advantage of the ability of a polarized substance e.g. water to act as a solvent. Alcohol cannot do this. It does not break down when it is dissolved in water.
