An Introduction to Qualitative Analysis Purpose: Tests the ions of Mg2+‚ Ca2+‚ Sr2+‚ and Ba2+‚ and identify them separately. By using these observations‚ identify the unknown ion. Then tests the ions of SO42-‚ CO32-‚ Cl-‚ and I-‚identify them separately‚ and use the observation to identify the unknown. Procedure Part I - Qualitative Analysis of Group 2 Elements Mix 0.02M K2CrO4 with each Mg(NO3)2‚ Ca(NO3)2‚ Sr(NO3)2 and Ba(NO3)2 together. Secondly‚ mix 0.1M (NH4)2C2O4 instead

is held up by a chain of subunits called amino acids that are connected by peptide bonds. Protein structures are formed by four levels of folding. The primary structure is the linear sequence of amino acids. The secondary structure describes the folding of alpha helixes and beta pleated sheets. The tertiary structure represents the overall shape of the protein and the quaternary structure only occurs in a protein consisting of more than one amino acid chain. When the shape‚ the structure or

point range was determined to be 109-111°C. The liquid unknown was purified by simple distillation and its boiling point was determined to be 95°C. An IR spectrum was collected for each of the purified compounds; the solid was determined to be 3-toluic acid and the liquid was determined to be 2-heptanone. Introduction Extraction is one way of purifying a substance. In an extraction‚ a solute is transferred from one solvent to another. Extractions depend on polarity and solubility; polarity is the

Experiment # 8 Qualitative Analysis of Cations Objectives Part I: Separate a mixture of known cations: Pb2+‚ Fe3+‚ Al3+‚ Cu2+‚ and Ca2+ into individual ions. Perform a series of tests to become familiar with reactions characteristic of each cation. Part II: Separate and identify individual cations in an unknown solution containing a mixture of up to five cations. Use information gathered in part I to identify the cations.
