Streszczenie

In the present article the applicability of the Pasynski method of determi-nation of hydration numbers of simple organic compounds in aqueous solvents of fixedpH at 25◦C from speed-of-sound and density measurements is tested and discussed.It was shown that for solutes which do not undergo protolytic reactions with a solventthe resulting values of hydration numbers are independent on the system pH—forthese solutesnhcan be determined both in pure aqueous solutions and in mixturescontaining ions. For solutes which undergo reactions with an acid or base, the Pasyn-ski method yields hydration numbers which are a combination of compressibilities ofsubstrates and products of occurring reactions.
