Abstract. This paper comprises an analysis of solutions of such salts as: sodium chloride NaCl,

potassium chloride KCl, sodium sulphate Na2SO4, ammonium chloride NH4Cl, and

hexylamine hydrochloride C6H15N˜HCl. The objective of the paper was to determine the

Critical Coalescence Concentration (CCC) of four inorganic and one organic salts. The obtained CCC values were similar to those already existing in literature. Also, in this paper the CCC values of investigated inorganic salts were compared in terms of their ionic strength. The results showed that, except KCl, there was a relationship between CCC and ionic strength.
