You were pulled over by the police and they wound an unknown white powder in your car. You claimed it was nicotine residue (N), however the police believe you are trafficking morphine (M). To prove yourself innocent you break out your supreme chemistry knowledge and conduct the following. First, knowing that they both form salts that can dissolve in water, your form the: Chloride salt (NCl: MW=198.7 g/mole) of the nicotinium ion N+ Ka=1.0x10-8 Sodium salt (NaM: MW=317 g/mole) of the morphinate ion M- Kb=7.0x10-5 You then dissolve 3.17 grams of the unknown white powder in 100 ml of water and measure the pH to be 4.4. *Using the information for the morphinate ion, prove that you were not breaking any laws.

Question
You were pulled over by the police and they wound an unknown white powder in your car. You claimed it was nicotine residue (N), however the police believe you are trafficking morphine (M). To prove yourself innocent you break out your supreme chemistry knowledge and conduct the following.
First, knowing that they both form salts that can dissolve in water, your form the:
Chloride salt (NCl: MW=198.7 g/mole) of the nicotinium ion N+ Ka=1.0x10-8
Sodium salt (NaM: MW=317 g/mole) of the morphinate ion M- Kb=7.0x10-5
You then dissolve 3.17 grams of the unknown white powder in 100 ml of water and measure the pH to be 4.4.
*Using the information for the morphinate ion, prove that you were not breaking any laws.
