Ph measurement meaning
In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H ions) are measured to have lower pH values than basic or alkaline solutions. WebbThe pH Essentials Guide is intended as a first introduction to the practice of pH measurements. The basic knowledge that is needed to understand a pH measurement is given. The tools necessary for pH measurements are explained and a step-by-step guide to perform pH measurements is provided. Additionally, some practical tips and tricks are ...
