What happens to the solubility of an ionic compound as ionic strength of the solution increases up to ~0.5 M)? Why is there a correlation between the solubility of an ionic compound and the ionic strength of the solution? a. The increase in ionic strength increases the concentration of aqueous ion pairs. b.The increase in ionic strength decreases the concentration of aqueous ion pairs. c.The increase in ionic strength increases the ionic atmosphere around an individual ion, shielding it from other ions, decreasing the tendency for ions to bind together. d.The increase in ionic strength increases the ionic atmosphere around an individual ion, increasing the contact between ions, increasing the tendency for ions to bind together.
Calculate the pH of a solution resulting from mixing together the following: a) 37ml of HCL 0.1M+33ml of NaOH 0.03M b) 55ml of HNO3 0,7M+88ml of KOH 0.8M c) 170 ml of H2SO4 0,44M_29ml of NaOH 1.2M d)76 liters of HBr 0.01M+2 liters of Mg(OH)2 2.1M.
