For argentometric determination of halogens (X) what is the end-point pAg value for iodide, bromide and chloride determinations pK_sp(Agl) = 16.07, pK_sp(AgBr) = 12.27, pK_sp(AgCI) = 9.75 For a solution of 0.01375 M MgS0_4, 0.0040 M Ca(N0_3)_2, 20 mu M HCI what is the pH The hydrated radius of hydronium ion is 900 pm. pH = -log(a_H+) log gamma = -0.51z^2sqrt 1/1 + (alpha sqrt 1/305)
