Carbon dioxide reacts with water to produce carbonic acid. The double arrow means that carbonic acid breaks down pretty readily to form carbon dioxide and water again. A hydrogen atom from the ...

Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions ...

Adding water to an acid or base will change its pH. When an acidic solution is diluted with water the pH of the solution increases gradually, making the solution less acidic as more water is added.

which holds the promise of a sustainable and carbon-free energy solution. However, conventional catalysts often struggle to maintain both high performance and stability in acidic environments.

Hydrogen energy is considered a promising solution with high energy density ... the HER electrocatalytic activity of PtCo/MXene in an acidic medium. The research is published in the journal ...
