Question

prepare various solutions with different densityby adding some drops of ink in different amounts of water and explain the principle involved in it​

Answer 1

Answer:

Fill half a beaker with water.

Put a watch glass on the mouth of the beaker

Put few drops of ink on the watch glass.

Now start heating the beaker. We do not want to heat the ink directly. You will see that evaporation is taking place from the watch glass.

Continue heating as the evaporation goes on and stop heating when you do not see any further change on the watch glass.

Observe carefully and record your observations.

Fig.1

We find that ink is a mixture of a dye in water. Thus, we can separate the volatile component (solvent) from its non-volatile solute by the method of evaporation.
