(chemistry)
An arrangement of anions or cations in order of decreasing ability to produce coagulation when their salts are added to lyophilic sols. Also known as lyotopic series.

Addition of Hofmeister series of salts enhances the formation of complex between PVA-PSSNa which in turn decreases the LCST of mixture of polymers.
The decrease of the LCST is in the order Na2SO4 (less than) NaF (less than) NaCl (less than) NaClO3 (less than) NaNO3 (less than) NaBr (less than) NaSCN which is opposite to classical Hofmeister series.
Key words: Poly (vinyl alcohol), Poly (Sodium 4-Styrene Sulphonate), LCST, phase separation and Hofmeister series.
The influence of inorganic aqueous salt solutions on synthetic or natural hydrophilic polymeric materials can be deduced from the Hofmeister series.
Looking for possible effects of counterions, I selected perchlorate as a chloride substitute because it is near the end of the Hofmeister series, which ranks ion effects on soluble proteins (6).
The Hofmeister series (23) ranks the tendency of different salts to perturb the denaturation temperature of proteins.
The effect of ions of the Hofmeister series on the LCST of IPAM-100 (24) is discussed in the accompanying paper (8).
The % DR in aqueous solutions also follows the order of the Hofmeister series.
