Acetylsalicylic acid is extracted from BC powder. The BC powder components per 1 g are: 700mg acetylsalicylic acid, 200mg salicyclamide, and 100mg Caffeine. After the
Acetylsalicylic acid is extracted from BC powder. The BC powder components per 1 g are: 700mg acetylsalicylic acid, 200mg salicyclamide, and 100mg Caffeine. After the experiment, 0.348g of dried acetylsalicylic acid is extracted. The dried acetylsalicylic acid is placed in the oven. It begins to melt at 135 degrees Celsius, and the end melting point is 140 degrees Celsius. The theoretical melting point is 135 degrees Celsius.
(a) Calculate the amount of acetylsalicylic acid isolated from BC powder.
(b) Calculate the percent recovery. For this you will need to consider the composition of BC powder.
(c) Comment on the purity of the isolated sample by discussing the melting range recorded. Then suggest a modification to the experiment procedure that would improve the percent recovery.
