Water pH Measurement

pH or acidity is used to express the degree of acidity (or alkalinity owned by a solution. That meant “acidity” is the concentration of hydrogen ions (H +) in water solvent. The pH values ​​ranging from 0 to 14. A solution is said to be neutral if it has pH = 7. The pH value> 7 indicates alkaline solution properties, ...
