Respuesta :

- Acids are substances that form H^+   ions when dissolved in water.

- Bases are substances that form OH^-   ions when dissolved in water.



- Substances with a Low pH ( < 7) have more H^+  ions are classified as Acids.

- Substances with a Higher pH ( > 7) have more OH^-   ions and are classified as Bases.



The pH of a solution/substance is a measure of the molar concentration of hydrogen ions in solution/substance and as such, is a measure of the Acidity or Basicity of the solution/substance. 

The letters pH stands for " Power of Hydrogen." and  the: 

Numerical Value: is defined as the Negative Base 10 Logarithm of the Molar Concentration of Hydrogen Ions.

pH = log10[ H^+]
