Ancient microbes illustrate a particular kind of respiration in which carbon dioxide and hydrogen are combined to form acetic ...

Scientists at Goethe University uncover how the oldest enzyme in cellular respiration functions – opening the door to potential CO₂ removal from exhaust emissions. Animals, plants, and many other livi ...

A new study suggests battery recyclers could reduce environmental impacts and costs by replacing harsh chemicals with a neutral solvent to recover minerals.

If the hydrogen ion concentration increases by a factor of 100 (10 2), the pH decreases by 2. A solution of 0.8 mol/dm 3 hydrochloric acid has a pH of 0.1. Predict its pH when it is diluted to 0. ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a ...

A team of scientists have elucidated an ancient mechanism of cellular respiration. To that end, they studied bacteria that feed on the gases carbon dioxide and hydrogen, and turn them into acetic acid ...

All alkaline solutions contain more hydroxide ions than hydrogen ions. Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base ...

A hydrogen atom from the carbonic acid bonds to the carbonate ion in ocean water and creates a bicarbonate ion (HCO-3) which the shell-making organisms can’t use.

Lime is usually added to acid soils to increase soil pH. The addition of lime not only replaces hydrogen ions and raises soil pH, thereby eliminating most major problems associated with acid soils but ...

ION exchange resins, in the hydrogen form, appear to offer several advantages as acid catalysts, such as the possibility of their continuous or repeated use without renewal, and their easy removal ...
