Answer to Question #52493 in Physical Chemistry for atinu

Question

given swimming pool water with following initial quality just after addition of bleach and hcl to lower the ph to desired range
ca2+ 1E-3 M [hco3]=2E-3M na+ 2.05E-3M cl-2.00E-3 M ocl- 5E-5 M Ph=7.3

a. find the ph after watet comes to equilibrium with the atmospheric concentration of 350 ppm co2 (g) asumming the free chlorine doesnot dissipate by conversion to CL-
b. find the PH after the water comes to equilibrium with an atmospheric concentration of 350 ppm co2(g) assuming the free chlorine does dissipate by catalytic reduction (by UV radiation in sunlight ) to CL- assuming the other half reaction is the oxidation of water to oxygen .
