Add NaCl to your reaction mixture, heat it, and then cool it again.

The photo shows a laboratory scale with a small plastic weighing boat on top. The contents of the weighing boat are not visible, but the screen on the scale reads “0.4999 g.” A gloved hand holds a small brown glass reagent bottle next to the scale. The label on the bottle reads “Sodium Chloride.”

after cooling on ice

The photo shows a small Erlenmeyer flask held in the air at an angle by a gloved hand. The flask contains a moderate amount of dark purple substance, although its nature (solid or liquid) is difficult to discern. Several chunks of ice cling to the outside of the flask.

Isolate and analyze the product.
