LAB 3: QUALITATIVE ANALYSIS Part 2- ANIONS Sameera Feroz Butt Lab Partner: Ram Soni Thursday January 30‚ 2014 Leilani Morales CHEM1131-02 OBJECTIVE The objective of this experiment was to use qualitative analysis to determine the chemical characteristics of four known anions by systemic confirmatory testing. The chemical characteristics observed were to be used to identify an unknown sample. Sulphuric acid was to be added to a carbonate solution and an effervescent reaction would

Experiment # 1– Qualitative Analysis of Cations Rachel Sorrells Gretchen Diede TA: Kunal Punjabi February 16‚ 2017 RESULTS & DISCUSSION The purpose of this experiment was to utilize two different methods of qualitative analysis to determine the identity of two unknown cations in an unknown solution. The experiment required knowledge of solubility rules and demonstration of such in the laboratory setting for the first method of qualitative analysis. The second method of qualitative analysis was the performance

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

TITLE: Qualitative Analysis Of Cations: Ca2+‚ Ba2+‚ Mg2+‚ Zn2+ and Al3+ OBJECTIVE: • To identify the cations in known and unknown samples. • To construct a logical flow chart for identifying the components of a mixture of unknown cations. INTRODUCTION: In this experiment we will study about qualitative analysis of cations: Ca2+‚ Ba2+‚ Mg2+‚ Zn2+ and Al3+. Qualitative analysis is an analytical procedure in which the question ‘what is present?’ is answered. In a systematic qualitative analysis

Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures

EXPERIMENT TWENTY Qualitative Analysis of Anions Analysis of Solutions Containing the Ions Cl-‚ Br-‚ l-‚ SO42-‚ CO32-‚ and NO3- This experiment continues the qualitative analysis begun in Experiment 19. Here we will be analyzing solutions to determine the presence of anions. The same techniques that were used for the cation analysis must be used for the anions. If you have not carried out Experiment 19‚ read the introductory section before starting this experiment. The major difference
