QUALITATIVE TESTS FOR SOME CATIONS II CHEMISTRY 11.1 OCTOBER 5 2013 QUALITATIVE TESTS FOR SOME CATIONS II I. Introduction Qualitative analysis schemes are often based on selective precipitation of different cations. By carefully selecting reagents and conditions for reactions‚ groups of ions can be separated on the basis of their reactivity and the solubility of their salts. This enables the experimenter to use simple techniques with standard laboratory equipment‚ as well as to learn

Abstract: A qualitative analysis experiment was conducted to determine the identity of an unknown aldehyde or ketone. The tests include a Tollens test‚ a Schiff test‚ an iodoform test‚ and a derivative melting point test. The data of the first three tests was inconclusive. The final derivative melting point test was utilized to successfully determine that the unknown was the ketone‚ Propiophenone. Introduction: Qualitative analysis is a method or series of methods used to determine the

Qualitative vs Quantitative analysis Qualitative analysis: Richness and Precision The aim of qualitative analysis is a complete‚ detailed description. No attempt is made to assign frequencies to the linguistic features which are identified in the data‚ and rare phenomena receives (or should receive) the same amount of attention as more frequent phenomena. Qualitative analysis allows for fine distinctions to be drawn because it is not necessary to shoehorn the data into a finite number of classifications

Payback Method The payback method is useful because of its simplicity. You simply take the expected cash inflows per year expected after the initial investment and find the breakeven point in where the cash inflows equals the initial investment. Whenever that breakeven point occurs on your timeline‚ that is your payback period. Let us suppose an initial investment for a project is $1.3 million‚ the expected cash inflows for the first two years totals $850‚000‚ and the third year is expected to

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-.
