Question

What method would you use to obtain pure water from the mixture of ink and water? State with the reason, what happens to the colour of the mixture of water and ink during the process?

Answer 1

Distillation is the method use to obtain pure water from the mixture of ink and water.

This is a process of separating two substances mixed together. Water vaporizes at a lower temperature than the ink pigment so if you heat them, the water evaporates, leaving the ink pigment in the flask.
