The Ky of Agl is 8.3 x 10-7. Refer to the table of activity coefficients at various ionic strengths as needed. [1] =

Answer 1

Given data: [AgNO₃] = 0.0010M Ksp for Agi = 8.3x 10-1? Silver nitrates ionizes as follows:- AgNO3 → Ag+ + NO3 Silver jodide ionizes as follows:- AgI Agt ti- ksp: [Ag+ J£I-] Let us assume (Agf] =[I-]=5 so, 8.38 10-17=52 [s] = 9.1110-9 Now, AgNO₃ solution is used, there is excess Agt. Concentration of Ag+= [0.001] as it fully ionizes into its ions. Above equilibrium shifts to Agi side due to Common ion effect of Agt. 8.3x10-17 = SX 0.001 in s= 8.3 x 10-20 Concentrationaf I in 0.001M AgNO3 saturated with Ag I is 8.3 x 10-20
