  1. Lecture 1 Analytical Chemistry CHE301

  2. Synthetic Chemistry Analytical Chemistry To find out what is it To make a new stuff “white powder”

  3. Quantitative Qualitative to identify This white powder is NaCl to detect There is a trace admixture of iodine in this sample to analyze to determine X in a sample to quantify to measure 0.375 mg/mL caffeine Run assay determination quantitation Composition, %%: Cu, 85.34(3); Zn, 11.23; Sn, 1.02(2); Fe, 0.123(2); Mn, 0.058(5);Ni, 0.229(5); …

  4. Analytical chemistry sequence @ BSC Titrations with NaOH, EDTA, KMnO4, K2Cr2O7, , I2 Some separations and photometry CHE111-112 Identification of organic compounds; IR, NMR, GC CHE203-204 Analytical Chemistry itself: gravimetry, titrations, electrochemistry and spectrophotometry CHE301 CHE403 Instruments, how they work and how to operate them Biochemistry, Advanced Analytical Chemistry, Analytical Toxilcology, and Inorganic Chemistry - More about analytical methods
