Q & A
Chemicals have the chemical property of acidity or alkalinity that is important for safe contact, chemical reaction and physical mixture.
Determination of the acidity-alkalinity by acid-alkali reaction is crucial in the understanding of chemical functions.
The principle of pH meter
Advantage and disadvantage of pH meter
Advantage
Wide measurable range
Need short time to measure pH
Simple control and continuous measure
Disadvantage
Fragile glass electrode
High internal resistance of electrode
