The following are various applications of potentiometry
It is used for the determination of equilibrium constant
Determination of ionic product of water
Determination of dissociation constant of acids
It is useful for known the activity coefficient
To study the solubility and solubility product of sparingly soluble electrolytes
The potentiometry to know the valency of metal ions
It is most helpful for the determination of instability of complex ions in complexometry
The potentimetry helpful for the determination of Ca, K, Cl ions in the body fluids like blood, plasma, sweat and serum.
Potentiometry useful in the detergent industry to study the effect of Ca, Ba, F on water.
In Agriculture to estimate K,Ca,Cl,CN,NO3, NH3 in soil, fertilizers, feed stuffs and plant materials.
The potentiometry helpful for determination pollutant in drinking water.
Determination of NO3, NO2 in meat preservatives
NaCl content in meat, fish, dairy products and fruit juice
Ca content in dairy products, beer, wines and brewing solutions
K content in fruit juices, beer and wines
Corrosive effect of NO3 in canned food
Paper manufacturing – S and Cl in pulping and recovery cycle liquors
Explosive- F, Cl and NO3 in chemical warfare agents and combustion products.
Health: Determination of pH of blood for diagnosis of acidosis or alkalosis
Pharmaceutical industry: To determine the pH of given chemical agents and also in the detection of end point in potentiometry titration of certain drugs like amoxicillin, propranolol.
