For the first time, scientists have observed water molecules splitting in real time to form hydrogen and oxygen. And right ...

Water might have formed much earlier than previously thought. Computer simulations show supernovae produced significant ...

A group of scientists led by Dr Daniel Whalen of the University of Portsmouth’s Institute of Cosmology and Gravitation have ...

The positive areas of the water molecules surround the negative Chloride ions. The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules ...

Water molecules can break down into hydrogen ions ... To make the pH change by 1, a tenfold dilution is required (eg adding 9 cm 3 of water to 1 cm 3 acid). The acid is becoming less acidic.

Oil is more dense than alcohol, but less dense than water. The molecules that make up the oil are larger than those that that make up water, so they cannot pack as tightly together as the water ...

The water concentration can be thought of as the proportion of a solution that is water. Solutions with a high concentration of solute molecules, such as sugars or salts, have a low concentration ...

Splitting water molecules takes more energy than calculations suggest, and is a key roadblock to cheap hydrogen fuel production. Now, scientists have discovered why.
