Put 10 mL ink in a flat bottom conical flask. Add boiling chips to prevent bumping. Fit a
stopper with a delivery tube reaching half way down a collecting test-tube or an U-tube, in a
beaker of water. Heat the ink with a Bunsen burner flame. Drops of a colourless liquid
appear in the collecting tube. Identify the liquid as water by its action of turning white
anhydrous copper sulphate to blue hydrated copper sulphate. Do not allow ink to froth up or
splash into the delivery tube.
