Now using a pipette transfer small amounts of solution in Jar A into Jar B.<br />
A.<br />
Stir and check the pH of contents in Jar B after each transfer of lye solution until the solution in Jar<br />
B reaches a pH of ~11-12.<br />
B.<br />
Shake the jar but be careful of pressure that will build up inside the jar. Release the lid and vent<br />
often! The solution will change a gray color as the alkaloids are turned from acid salts to free<br />
base. It may resemble a thick gel. Then the solution will turn black and slippery as you add more<br />
base. The jar will heat up during this process.<br />
You have now formed the free base alkaloids that are soluble in non-polar solvents.
