You want to analyze a silver nitrate solution. (a) you could add hcl(aq) to the solution to precipitate out agcl(s). what volume of a 0.150 m hcl(aq) solution is needed to precipitate the silver ions from 15.0 ml of a 0.200 m agno3 solution? (b) you could add solid kcl to the solution to precipitate out agcl(s). what mass of kcl is needed to precipitate the silver ions from 15.0 ml of 0.200 m agno3 solution? (c) given that a 0.150 m hcl(aq) solution costs $39.95 for 500 ml and that kcl costs $10/ton, which analysis procedure is more cost-effective?
