Question

Is hydrogen an acid or base?

Answer 1

Explanation:

The$\mathrm{pH}$ value indicates whether a substance is acidic or basic.

1. The$\mathrm{pH}$ scale runs from$0$ to$14$. If the$\mathrm{pH}$ value is between $0$ and $7$ it is acidic and if the $\mathrm{pH}$ value is greater than$7$ it is basic.
2. A high concentration of hydrogen ions results in a low$\mathrm{pH}$ (acidic) value, while a low concentration of hydrogen ions results in a high $\mathrm{pH}$ (basic).

Hence, hydrogen is an acid, not a base.
