- Ksp mg (on) = 6x10 to pn= 11 nt = 10ll on = 103 mg CH2 - Mgat t 2 (on) Ksp = (mglp? Can ² 6x16 = (mg af] Clo3} 10-6 Mg 2p]Isp of C COH), = 615x1556 if PH=11 pan=3 [an] =103 then Ksp = [lazip] Cont? 6.5*100 = [Get ] [103]2 [624] = 65.As the Ksp of GloH), is higher G24 will remain in sohible form g ito solubility is higher than mg at At given pH value I. mg
