THIN LAYER CHROMATOGRAPHY OF ANALGESICS
Introduction: Over-the-counter analgesics typically contain one or more of the following active ingredients: acetaminophen, aspirin, caffeine, ibuprofen, phenacetin, or salicylamide. Thin layer chromatography (
Quiz 4 Solutions 1. For a closed pipe successive harmonics differ by 2f1 as only odd harmonics appear. So 2f1 = 630 450 = 180 giving f1 = 90 Hz. 2. For a closed pipe, L = n/4 (n odd) so = 4L/n = v/fn. This gives for n = 1 f1 = v/4L and substituting
QUIZ 1 Solutions 1. For a charged conducting sphere, from the surface of the sphere r = R0 to , the potential is that of a point charge Q, V = kQ/r. So given V at the surface, Q = R0V/k giving Q = 0.25 x 540/9 x 109 = 15 x 10-9 C. Then the surface ch
