Answer:
slowly adding aqueous silver ions to a solution containing halide ions
Explanation:
We know that silver halides are insoluble in water. This means that they do not dissolve in water.
The precipitation of halide ions occurs according to the reaction;
Ag^+(aq) + X^-(aq) ------>AgX(s)
When a solution of aqueous silver ion is slowly added to a solution containing a mixture of halide ions, a homogeneous mixture of different silver halide precipitates is generated.
