Question

(a) Describe any evidence that a chemical reaction occurred when you added 6 M HCl to the solution of sodium acetylsalicylate. (b) Explain why the changes that you observed took place. please answer both parts (a) and (b) with drawing stractures as well and explantion.

Answer 1

Ans---

a) When we add HCL to the sodium acetylsalicylate a fizzing sound will be come out . This is because there will be a rapid change in temperature and a gas form,HCl will release during this process through gas fumes. At the end of the reaction a solid participate will be form which originate from the salt.

b) we know,  sodium acetylsalicylate is a basic solution when we add HCl to sodium acetylsalicylate , it makes the chemical less soluble than water. This causes aspirin solute residue to be left behind. on the otherhand When Sodium Bicarbonate is mixed with the DCM, aspirin, its reacted with the aspirin to form a salt because SodiumBicarbonate is a base. Since the aspirin is a weak acid, and SodiumBicarbonate is a weak base, the reaction formed a conjugate base anda conjugate acid. The changes occurred because the strong acid,(HCL) reacted with the conjugate base of the solution.
