Understanding the unusual properties of water?
Water: the weirdest liquid on the planet:
Water: the weirdest liquid on the planet Water is a strange molecule, and no matter how many weird things we discover in it.
It seems that there are always unexpected surprises that may happen that await us even after centuries of searching it.
New study in United States:
In a new study, scientists in the United States discovered that under certain conditions.
Water can automatically produce hydrogen peroxide,which is a special feature of basic chemistry hidden from public view, which has not been noticed in some way until now.
Chemist Richard Zare:
Chemist Richard Zare from Stanford University says: “Water is one of the most common substances in existence.
It has been studied for years and years and we may think that there is nothing extra to know about this molecule, but here we have another surprise.”
Scientists have observed this phenomenon only in pure water, not in any form of water.
According to research:
According to the research team, spontaneous production of hydrogen peroxide can occur when water is dissolved into microscopic droplets of 1 to 20 μm.
One micrometer is just one-thousandth of a millimeter, so we’re talking incredibly small droplets here.
On this infinite scale, the spontaneous formation of hydrogen peroxide appears to occur without the need for anything other than water to exist.
Scientists say in their new research:
“This process does not require any chemical reagent, catalyst, applied electrical voltage, or radiation.
The mere presence of pure water in the form of microscopic droplets in the air is necessary for the appearance of hydrogen peroxide.”
The team discovered this surprising result by accident in previous research, while investigating how to make gold nanoparticles and nanowires using water droplets.
These experiments revealed that the microscopic water droplets not only accelerate the synthesis of gold nanostructures, but also cause their spontaneous formation.
In the new research, a team visiting conducted a number of tests, including spraying small samples of pure water onto a test strip, which turns blue when hydrogen peroxide is present and is already blue.
Another experiment revealed that the yield of hydrogen peroxide is inversely proportional to the size of the microscopic droplets.
In other words, smaller microscopic droplets produce particles in higher concentrations.
But why does this happen in the first place? How?
It’s hard to know for sure, but researchers speculate that the spontaneous oxidation of water is more likely to occur due to the presence of a strong internal electric field at the interface between the water and air of the microscopic droplets, as the electric field generates the hydroxyl radicals, which in turn combine into hydrogen peroxide.
While it will take future research to test this hypothesis, the team maintains that the production of hydrogen peroxide in and of itself is unequivocal and may lead to new and more environmentally sustainable ways to manufacture this common chemical.
“We would like to point out that this discovery opens up many innovative opportunities, including the environmentally friendly and inexpensive production of hydrogen peroxide,
Environmentally friendly chemical manufacturing, safe cleaning and the food industry,” the researchers add.
For Zar himself – an influential chemist who has won multiple awards with no fewer than 11 honorary doctorates – this discovery is as important as it is surprising. “I think it could be one of the most important things I’ve ever done,” he says.
