In the procedure of plating metal with silver the silver, Ask an Expert

Academics

In the procedure of plating metal with silver the silver ions are recovered from the wastewater from the plating bath by precipitating out silver chloride, AgCl. Kso for AgCl is 1.8*10-10. Presuming complete dissolution of NaCl, explain how much NaCl (in g) must be added per liter of wastewater to make sure that the soluble silver concentration is less than or equal to 1 µg/L? Presume low pH so you can ignore any complexion of silver with OH-).
