A determine the activity coefficients for h and oh- in a, Ask an Expert

Academics

a. Determine the activity coefficients for H+ and OH- in a 0.0300 M aqueous solution of MgCl2 using the Debye-Huckel Limiting law at 25oC. Determine the same activity coefficients for H+ and OH- in the same aqueous MgCl2 solution using the Extended Debye-Huckel law. -log ? = [ A z2 I1/2 ] / [ 1 + B d I1/2 ] A = 0.5085 and B = 0.3281 for water at 25oC and d = 9 for H+ and 3 for OH-
