Miscibility

Under Miscibility refers to the qualitative statement that in the mixing of at least two different liquids this fully mix to form a single homogeneous phase.

For example, let water and lower alcohols in any proportion mix, water and benzene on the other hand form two phases, one rich in water and a benzene -rich. Also in the benzene-rich phase, however, is included (about 0.25 mole percent at 25 ° C) and in the water-rich something benzene (0.04 mole at 25 ° C) water. This itself can be considered a very limited extent as miscible this system.

The miscibility is dependent on some mixtures significantly on the temperature. One example is the mixture of methyl vinyl ketone ( 3-buten -2-one ) and water miscible below 28 ° C and above 84 ° C but not between these limits.

A great influence on the miscibility of two liquids has its polarity so can be especially liquids mix with each other, their polarity fits together.
