. The determination in problem 15-9 was modified to use the standard addition method. In this case, a 4.236 g tablet was dissolved in sufficient 0.10M HCl to give 1.00 L. Dilution of 20.00 mL aliquot to 100 mL yielded a solution that gave reading of 448 at 347.5 nm. A second 20.00 mL aliquot was mixed with 10 mL of 50 ppm quinine solution before dilution to 100 mL. The fluorescence intensity of this solution was 525. Calculate the percentage of quinine in the tablet.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
