Why patient with achlorhydria can dissolve aspirin rapidly?
Patients with achlorhydria have low or absent stomach acid, which is needed to break down aspirin for absorption. Without stomach acid, aspirin can dissolve quickly in the stomach and be absorbed more rapidly into the bloodstream, potentially leading to increased systemic effects and side effects.
Solution of water and aspirin an acid?
Yes it will be weakly acidic. Aspirin's scientific name is acetylsalicylic acid, with a pKa of 3.5. This would mean that for a solution of 0.1 M aspirin, the pH of the solution would be approximately 2.26.
What color does blue litmus paper turn when dipped in aspirin?
Blue litmus paper will turn red when dipped in a solution with a pH below 4.5, indicating acidity. Aspirin (acetylsalicylic acid) has a pH of around 3.5, which is acidic. Therefore, blue litmus paper dipped in aspirin will turn red.
Why take buffered aspirin?
Buffered aspirin is coated to help protect the stomach lining from irritation that can be caused by regular aspirin. This coating can help reduce the risk of stomach upset and potential damage to the stomach. Buffered aspirin may be recommended for individuals who are more sensitive to the stomach side effects of aspirin.
Can aspirin purity be tested using indicator and if so what one?
Aspirin purity can be tested using acid-base indicators such as phenolphthalein or bromothymol blue. These indicators change color based on the pH of the solution, allowing for a qualitative assessment of purity. However, more precise quantitative methods such as spectrophotometry or chromatography are typically used for accurate purity testing of aspirin.
What pH does aspirin have?
The pH is around 3-4
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.
What is the pH of asprin?
The pH of aspirin is approximately 3.5, making it acidic in nature.
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.
How you would find out is soluble aspirin is acid or alkali?
To determine if soluble aspirin is acidic or alkaline, you can dissolve it in water and test the pH of the solution using pH paper or a pH meter. Aspirin, or acetylsalicylic acid, is a weak acid, so you would expect the pH to be below 7, indicating acidity. Additionally, you could observe its reaction with baking soda (sodium bicarbonate), which would produce bubbles of carbon dioxide if it is indeed acidic.
What color of pH strip is aspirin?
Aspirin, which is acetylsalicylic acid, typically has a pH around 3 to 4 in solution. When using pH strips, this acidity would generally correspond to colors indicating an acidic range, typically a light orange to yellow. The exact color may vary depending on the specific pH indicator used on the strip.
Why is sodium hydroxide added into the conical flask containing a analgesic or aspirin?
to decrease ph
Why does cabbage juice change pink in aspirin?
Cabbage juice contains a pH indicator called anthocyanin, which changes color in response to the acidity or alkalinity of a substance. When cabbage juice is mixed with aspirin, which is acidic, the anthocyanin reacts to the pH change, resulting in a pink color. This color change is a visual representation of the acidic nature of aspirin, demonstrating how natural indicators can be used to gauge pH levels.
Why patient with achlorhydria can dissolve aspirin rapidly?
Patients with achlorhydria have low or absent stomach acid, which is needed to break down aspirin for absorption. Without stomach acid, aspirin can dissolve quickly in the stomach and be absorbed more rapidly into the bloodstream, potentially leading to increased systemic effects and side effects.
Is aspirin absorbed in the stomach or intestines?
Aspirin is absorbed both in the stomach and the small intestine , for the former the cause lies beyond the fact that the gastric PH (1.5-2.5) is lower than the pka of aspirin (3.5) such that the ionization of aspirin is so much limited and the unionized and subsequently the lipophilicity of aspirin increases so that it's easily absorbed into the gastric mucosal cells. for the latter , aspirin absorption is due to the large absorptive surface area of the small intestine despite the fact that the intestinal PH is higher than the pka of aspirin , but still the surface area help absorption of the unionized fraction of aspirin.
Why is an excess amount of Na OH added to the conical flask containing aspirin?
to decrease ph
Aspirin is an acid with pKa of 3.5 is aspirin more absorbed in stomach where pH is 1 or in small intestine where pH is 6?
Aspirin is absorbed from the stomach but most of it is absorbed from small intestines because of poor dissolution of acidic drug in stomach acid, high dissolution in intestinal contents, large surface area on intestines and good blood flow in intestines
