Question

What method would you use to obtain pure water from a mixture of water and ink

Answer 1

Answer: Distillation

Explanation: Separate ink from water using a process called distillation. 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.

Answer 2

Answer: Distillation

Explanation:

Distillation is the process of purifying a liquid by successive evaporation and condensation. Water vaporises at a lower temperature compared to the ink pigment, therefore, the mixture is heated to boiling so that the water evaporates leaving the ink pigments in the flask. The evaporated water can the be passed into a condenser which converts the water vapour into liquid.
