Question

When an impurity is introduced during the development of crystal lattice of a
precipitate the
phenomenon is called
1.post precipitation
2.supersaturation
3.co precipitation
4.complex formation​

Answer 1

Answer:

co precipitation.......

Answer 2

Answer:

when an impurity is introduced during the development of the crystal lattice of a precipitate the,

the phenomenon is called post precipitation  

post precipitation = it is a type of impurity which occurs due to high primary adsorption and supersaturated solution.

supersaturation =when the concentration of a solute increases the concentration specified by the volume equilibrium solubility.

co-precipitation = is specifically the precipitation of an unbound "antigen along with an antigen-antibody complex".

complex formation = complex forms when the positive or negative ions both involve.  

so, the option 1st is the correct answer.
