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 ...

Small changes in pH reflect significant shifts in acidity or alkalinity due to the exponential nature of the scale.

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 ...

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 ...
