Question

Please these are the questions based on the same experiment.

1 Is the percentage composition given on the original container correct?(Identifying the Unknown component of the counterfeit pharmaceutical.

2

Describe any evidence that a chemical reaction occurred when you added the 6M

HCl to the solution of sodium acetylsalicylate.

Explain why the changes that you observed took place.

Answer 1

Solution :-

Q1) If the experimentally calculated composition of the drug is same as it is labeled on the container then we can say that the percent composition of the original container is correct and if it is not mathcing with the original container composition then we can say that it is incorrect.

2) Sodium acetylsalicylate is the conjugate base of the acetyl salicylic acid therefore when it is reacted with the HCl then conjugate base takes the proton from the   HCl and will form the acetyl salicylic acid which will be porecipitate out as solid. SO the formation of the solid is the evidence that the reaction is ocuured.
