Yesterday I bought a package of pseudoephedrine at the pharmacy so I saw it in the water to remove the other compounds, but when I had the pseudoephedrine dissolved in the water and put it on the stove the water evaporated and there was just a slime at the bottom of the pan.
what did I do wrong? Could it be that the fire was too high? Can someone help me?
