Firstly place 100 to 150 mg of aspirin into a 125 ml conical flask. Next proceed to mix in 15 ml of 95% ethanol solution and add 2 drops of phenolphthalein indicator. Then use the titration method to mix this solution against a standard solution of sodium hydroxide from a burette. Using the value obtained from the titration calculate the molarity of the aspirin. Then calculate the ratio of the observed molarity of aspirin with its theoretical molarity and finally multiply this ratio with 100 to obtain the percentage purity of the aspirin sample.
What else can I help you with?
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.
Can aspirin affect blood alcohol levels?
Yes it can affect your BAC if you have been drinking. Aspirin inhibits your body's ability to metabolize alcohol.
What are the factors that affect the purity of a substance?
Factors that affect the purity of a substance include the presence of impurities, the method of preparation, storage conditions, and the sensitivity of the analytical technique used for testing purity. The more impurities present, the lower the purity of the substance, which can impact its properties and performance.
What factors affect the melting point of aspirin?

How would one determine whether a given sample of aspirin is pure or not?
One way to determine the purity of aspirin is through a melting point test. A pure sample of aspirin will have a specific melting point range, so comparing the observed melting point to the known range can indicate purity. Additionally, techniques such as chromatography or spectroscopy can be used to analyze the composition of the sample.
How is the process of making aspirin carried out in pharmaceutical manufacturing?
The process of making aspirin in pharmaceutical manufacturing involves combining salicylic acid with acetic anhydride in the presence of a catalyst, such as sulfuric acid. This reaction forms acetylsalicylic acid, which is the active ingredient in aspirin. The mixture is then purified, crystallized, and dried to produce the final aspirin product. Quality control measures are implemented throughout the process to ensure the purity and consistency of the aspirin tablets.
What is the difference between the melting points of the pure aspirin and the aspirin that prepared in lab?
The melting point of pure aspirin is typically around 135-136°C, while the melting point of aspirin prepared in a lab could vary depending on the purity of the synthesis process. Impurities in lab-prepared aspirin can lower the melting point or broaden the melting range compared to pure aspirin.
If you can not take aspirin can you take soma?
Yes. Soma (carisprodol) is a muscle relaxant unrelated to aspirin. It does not affect bleeding nor the stomach or kidneys but can cause sedation.
Will taking a baby aspirin affect the INR level?
Aspirin makes your platelets slippery and inhibits them from sticking together. Aspirin does not affect your INR but can still cause bleeding to be prolonged. Coumadin does affect INR and can be used effectively with aspirin if prescribed. (This is not to be taken as medical advice, but informational purposes). Source: Am a patient with antiphospholipid antibody syndrome, S/P bilateral pulmonary emboli and a TIA. Ten+ years of Coumadin, then Lovenox Injections. Now on coated enteric baby aspirin alone for a year, and INR is just 1.0. Hematologist monitoring.
Cortal dosage can affect the fetus?
Cortal is Aspirin and can cause fetal damage but not abort.
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?
Chromatography could be used to separate the components of the reaction mixture and identify if aspirin is present by comparing the retention time of the product to that of a known aspirin standard. If the retention time matches, it indicates the presence of aspirin in the reaction mixture. Additionally, chromatography can help determine the purity of the aspirin product by analyzing the intensity of the peak corresponding to aspirin.
Why can't pregnant women take aspirin?
Aspirin causes the platelets in our blood to become "slick" and can inhibit or affect our blood's clotting ability. Pregnant women should not take aspirin due to the fact that she could hemmorhage during spontaneous abortion or delivery.
