A mysterious white powder is found at a crime scene. A simple chemical analysis concludes that the powder is a mixture of sugar and morphine (C17H19NO3), a weak base similar to ammonia. The crime lab takes 10.00 mg of the mysterious white powder, dissolves it in 100.00 mL water, and titrates it to the equivalence point with 2.84 mL of a standard 0.0100 M  HCl solution. What is the percentage of morphine in the white powder?

Expert Answer

Step 1

Since it is reaching equivalence point means that all the weak base (morphine ) has reacted with the HCl.

Hence moles of HCl used = moles of morphine because 1 mole of HCl will neutralise 1 mole of morphi...
