The lithium concentration in serum taken from a patient being treated with lithium for manic-depressive illness...
The lithium concentration in serum taken from a patient being treated with lithium for manic-depressive illness was analyzed using flame emission spectroscopy. A sample of the serum gave a reading of 356 units for the intensity of the 671 nm red emission line. Then, 1.00 mL of a 10.1 mM lithium standard was added to 9.00 mL of serum. This spiked serum gave an intensity reading of 719 units at the 671 nm emission line. What is the original concentration...

Serum taken from a patient being treated with lithium for manic-depressive illness was analyzed for lithium concentration. A reading of 367 units was obtained for the intensity of the 671 nm red emission line. Then 1.00 mL of a 11.8 mM Lithium standard was added to 9.00 mL of serum, and this spiked serum gave an intensity reading of 806 units. What is the original concentration of Li in the serum?

Serum taken from a patient being treated with lithium for manic-depressive illness was analyzed for lithium concentration. A reading of 223 units was obtained for the intensity of the 671 nm red emission line. Then 1.00 mL of a 11.8 mM Lithium standard was added to 9.00 mL of serum, and this spiked serum gave an intensity reading of 624 units. What is the original concentration of Li in the serum?

Question 4 of 4 > Atomic emission spectroscopy and the method of standard addition are used to determine the Nat concentration and its uncertainty in an unknown sample. Increasing amounts of a 1.75 pg/mL standard Na' solution are added to a series of volumetric flasks containing 15.00 mL of the unknown solution. The volumetric flasks are then diluted to a final volume of 200.0 mL. Atomic emission spectroscopy is then used to measure the emission intensity of each solution Final...
