Part I

Obtain 12 M HCl on ice.

weighing out ice

The photo shows a small Erlenmeyer flask on the platform of a laboratory scale. The flask contains a small portion of ice and the screen on the scale reads “1.706 g.”

buret before HCl is dispensed

The photo shows a close up on the middle portion of a buret. The buret contains a clear liquid, the meniscus of which lies on the 52.00 mL marking of the buret.

buret after HCl is dispensed

The photo shows a close up on the middle portion of a buret. The buret contains a clear liquid, the meniscus of which lies on the 52.80 mL marking of the buret.

Add the dissolved amine to the acid.

The video shows a small Erlenmeyer flask immersed in a plastic tub filled with ice. The plastic tub is next to a magnetic stir plate, upon which a medium beaker filled with ice water houses a round bottom flask. The round bottom flask initially contains a golden yellow solution, but these contents are gradually pipetted into the Erlenmeyer flask. Throughout the gradual addition of the yellow solution, a glass stirring rod is used to mix the contents of the Erlenmeyer flask. The Erlenmeyer flask is then lifted out of the ice to reveal a small portion of very pale yellow, transparent solution at the bottom.

Leave the mixture stirring on ice.

The photo shows a small Erlenmeyer flask immersed in a medium beaker of ice water. The beaker sits on a magnetic stir plate and the Erlenmeyer flask is clamped in place. Through the ice in the beaker, we can see that the Erlenmeyer flask contains a small portion of cloudy white substance.

Prepare the nucleophile.
