Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the ...

The logarithmic characteristics of pH values are shown in the table below: each increment of the pH scale is equal to a tenfold difference in hydrogen ion concentration. Acidic solutions at 25° C have ...

The pH scale shows how acidic a substance is ... Reactions of metals with acids Acids react with some metals to produce salts and hydrogen. The salt name can be found from the name of the acid ...
