pH - Wikipedia

In chemistry, ,pH, is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower ,pH, values than basic or alkaline solutions. ,The pH, scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution. This is because the formula used to ,calculate pH, approximates the negative of the base 10 logarithm of the molar concentration of hydrogen ions in the solution. More precisely, ,pH, …
