Question

1. List the major variables affect the solvation entropy, S°, value of any dissolved ions in aqueous solution at 25 °C and what is the expected trend i ocreasing the variable value? The trend in Sm by its increase...r.. The trend So by ts increase:. 2. Calculate ApR and Δ67 for the reaction Ba(NO3)2(aq)2KCl(aq) BaCl2(s)2KNO3(aq and what would the correct Δ·Salvation be for Ba-ion in this reaction if you know that the Ba-radius in a crystalline BaCl2 is 133 pm?

Answer 1

Solvation is the process in which solute particles are surrounded by solvent molecules There are several factors affect the rate of solvation (i) temperature (ii) concentration (iii) surface are of solute (iv) conc^n of solvent etc when solute molecule come in contact with solvent molecule more oftenly the rate of solvation increases And also by increasing the temperature solvation entropy also increases
