In the procedure of plating metal with silver, the silver ions are healthier 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 how much NaCl (in g) must be added per liter of waste water to ensure that the soluble silver concentration is less than or equal to 1 µg/L? Presume low pH, so ignore any complexion of silver with OH-.
