Water has two different liquid phases; study reveals

Water, the fundamental source of human life has just proved to be a rather complicated one with a recent discovery showing that water exists in two distinct liquid phases.

Scientists from the Stockholm University found out that the two various phases of water contain huge differences in density and in structure. Publishing their findings in Proceedings of the National Academy of Science, scientists based their results on experimental studies by making use of X-rays.

According to Science Daily, one of the scientists Anders Nilsson expressed, "The new remarkable property is that we find that water can exist as two different liquids at low temperatures where ice crystallization is slow."

Scientists showed that water is actually a fluctuation between high and low density. Another researcher Lars G.M. Petterson said, "The new results give very strong support to a picture where water at room temperature can't decide in which of the two forms it should be, high or low density, which results in local fluctuations between the two."

He added, "In a nutshell: Water is not a complicated liquid, but two simple liquids with a complicated relationship."

X-rays from the Argonne National Laboratory near Chicago revealed the distinctiveness in structures, whereas, X-rays from DESY provided evidence that both forms were indeed liquid phases. “We have in particular been able to follow the transformation of the sample at low temperatures between the two phases and demonstrated that there is diffusion as is typical for liquids,” stated Fivos Perakis, one of the researchers.

Water itself is a complicated element; being able to exist in also plasma-like state apart from the three general phases, liquid water contains 70 various properties which are separate from other liquids.

Through this new discovery, researchers can better understand and generate enhanced purification and desalination methods. Futurism reported that on a large scale too, the discovery might enable scientists to see the affect of salts and biomolecules on water that are essential for life.
