The Total solution for NCERT class 6-12
Equal volumes of 0.002 M solutions of sodiumiodate and cupric chlorate are mixed together. Will it lead to precipitation ofcopper iodate? (For cupric iodate Ksp = 7.4 × 10–8).
Whenequal volumes of sodium iodate and cupric chlorate solutions are mixedtogether, then the molar concentrations of both solutions are reduced to halfi.e., 0.001 M.
Then,
Now,the solubility equilibrium for copper iodate can be written as:
Ionicproduct of copper iodate:
Sincethe ionic product (1 × 10–9) is less than Ksp (7.4 × 10–8), precipitation will notoccur.
