Constants I The Ka values for nitrous acid HNO2 and hypochlo

Constants I The Ka values for nitrous acid (HNO2) and hypochlorous (HClO) acid are 4.5 × 10-4 and 3.0 × 10-8, respectively.

Part B)

The other substance is NaClO

part B)

concentration of Ag+ = 1.8 x 10^-4 M

cocncentration of Pb+2 = 1.3 x 10^-3 M

Ksp of AgI = 8.52×10^–17

Ksp of PbI2 = 9.8×10^–9

here Ksp of AgI is less . so this is first precipitates.

AgI (s) ---------------> Ag+ + I-

Ksp = [Ag+][I-]

8.52×10^{–17 =} (1.8 x 10^-4) [I-]

[I-] = 4.7 x 10^-13 M

cocnentration of [I-] = 4.7 x 10^-13 M
