In quality control of raw materials for pharmaceutical production often used foul reactions to prove that raw materials in salt form containing the appropriate salt. Hydrochloride (eg. Amitriptyline hydrochloride) can be detected for example by precipitating the chloride ions like chloride. Chloride is sparingly soluble salt having solubility product, Ksp (AgCl) 1.6 · 10-10 at 25 ° C.

Question

In quality control of raw materials for pharmaceutical production often used foul reactions to prove that raw materials in salt form containing the appropriate salt. Hydrochloride (eg. Amitriptyline hydrochloride) can be detected for example by precipitating the chloride ions like chloride. Chloride is sparingly soluble salt having solubility product, Ksp (AgCl) 1.6 · 10-10 at 25 ° C.
 
a) Calculate the molar solubility of the silver chloride at 25 ° C.
 
b) there will be a precipitation of silver chloride in 10 mL of a solution of 20 mM amitriptyline hydrochloride is added 1 mL of 2 M silver nitrate (AgNO3). Justify your answer with calculations.
