Estella spilled some acetic anhydride on her hand. what should she do? How will Estella dispose of the prepared aspirin sample?
Homework Answers
Acetic anhydride is corrosive in nature thus, hands should be washed with water for 10 minutes and disinfectant soap should be applied. Covered the skin with emollient like mineral oil, plant oil which make the skin smooth and soft.
To dispose aspirin, mix the medicine with something undesirable like dirt, coffee grounds etc. Then place it in a plastic bag and throw it in dustbin.

QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...

Jane Scott, 21 years old, comes to the health-care provider to determine what she can do for mild dysmenorrheal. She states that this is not incapacitating, but creates discomfort during the first cky of her menses. She states that she does not want anything that makes her sleepy and that she has not tried any over-the-counter drugs. After further discussion with Ms. Scott, the health-care provider suggests that she try aspirin or ibuprofen as a beginning drug to see how...
