To determine its acid-dissociation constant, a student dissolved 2.00 g of aspirin in 0.600 L of water and measured the pH. What was the Ka value calculated by the student if thepH of the solution was 2.62? A 0.100 M solution of ethylamine (C2H5NH2) has a pH of 11.87.

WebMay 6, 2024 · pH is a measure of how acidic or basic a chemical is when it's in aqueous (water) solution. A neutral pH value (neither an acid nor a base) is 7. Substances with a pH greater than 7 up to 14 are considered bases. Chemicals with a pH lower than 7 down to 0 are considered acids. The closer the pH is to 0 or 14, the greater its acidity or basicity ... WebThe serum half-life of aspirin is approximately 20 minutes. The fall in aspirin concentration is associated with a rapid rise in salicylic acid concentration. Salicylic acid is renally excreted in part unchanged and the rate of elimination is influenced by urinary pH, the presence of organic acids, and the urinary flow rate.
WebThe influence of both moisture and heat on the stability of aspirin was investigated by a single pair of experiments, one with programmed humidity control and the other non-isothermal, rather than many standard isothermal studies, each at constant relative humidity. In experiments, we adopted the acid-base back titration method to measure the ...

WebAll steps. Final answer. Step 1/3. Give an explanation for any differences in the pH values of the four (4) samples recorded in the Table. The pH values of the four samples are different because they have different chemical properties and compositions. Salicylic acid and synthesized aspirin have a pH of 2.0 because they are both acidic.
