Question

uld calculate using ideal solution theory is not very large in this case Exercise group 9.2 ) Taking non-ideal effects into account, what is the pH of a o.0058 mol L" aqueous solution of HCl at 25°C? 2) The solubility of barium fluoride in water at 25 Cis 6.8 x 10 3 mol L-+. Using Debye-Hüickel theory, caleulate the solubility product of this compound. 2) Uric acid is a diprotic acid. The first acid Nissociation constant of uric acid has been measured as a function of temperature in a solution to which NaCl had been added to maintain a constant ionic strength of 0.15 mol L"1:1 T/eC 25 32 3742 Ka/10 5.50 6.17 646 7.41

Explanation / Answer

1. Concentration of H+ ions = 0.0058 M

pH = -log (0.0058) = 2.23657.

This is the pH of the sample considering it is a strong acid and that will dissociate completely.
