Okay, does this mean the original calculations I posted (see first post) would be correct to prepare the solution then? I can clarify with the person who wrote the directions by what the 50g refers too (either solute or solution)
This is my first time preparing a solution given the above directions. My instructions stated to prepare the solution gravimetrically. However, I could only figure out how to prepare the solution by volume, ie: 0.05 mL of 50 ppm Pb and 49.95 mL of HNO3. Would you suggest there is a more...
I would like to prepare 50.0 g of 50 ppb Pb standard solution in 1% HNO3 gravimetrically, in a 50.0mL plastic tube from a stock solution of 50 ppm Pb.
From what I understand, this is a dilution...so C1V1 = C2V2
I like working in mg/L more than ppb and ppm so I converted
50 ppb = 0.05 mg/L
50...
