  • Cu 2 And Cr 3 Ions
    2,358 words
    Qualitative analysis is used in the determination of the identity of a substance. It is different from quantitative analysis, which deals with the determination of the amount of a substance. In this experiment, qualitative analysis techniques are used to determine whether or not a sample contains a certain ion. When using this method, an unknown and a reactant are mixed. The result of the reaction leads to a conclusion about the presence or absence of certain ions in the unknown. Many ions react...
  • Stage Of Solution Development And Selection
    1,096 words
    Developing and Selecting Solutions Graham Parker's Structured Problem Solving Guide describes the problem solving process in four phases, one of which is Developing and Selecting Solutions (Phase 4). The other phases are not summarized here, however, it is noteworthy to mention that Phase 4 is the entering into solution development, whereas during the first three Phases of the process, specific problems of study have already been defined, a selection process is undertaken to decide which problem...
  • Na 2 C 2 O 4
    1,183 words
    Introduction For this experiment, we are going to determine the effect of temperature on solubility, to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically, the goal of this experiment is to prepare a saturated solution of Na 2 C 2 O 4 in water at different temperatures, determine the effect of temperature in solubility, and to apply Le Chatelier's Principle. We can do all this by simply titrating a certain amount of standard KMnO 4, and...

  • Average Molarity Of Permanganate Solution 2
    901 words
    Purpose: The purpose of this experiment is to determine the molarity of a permanganate solution through the use of red ox titration. Theory: The following are the reactions that take place in the experiment: Unbalanced: H 2 C 2 O 4 (aq) + MnO 4- (aq) CO 2 (g) + Mn 2+ (aq) H 2 C 2 O 4 Half-Reaction: H 2 C 2 O 4 (aq) 2 CO 2 (g) + 2 e- + 2 H+ (aq) MnO 4- Half-Reaction: 8 H+ + 2 MnO 4- (aq) + 5 e- Mn 2+ (aq) + 4 H 20 (l) Net Reaction: 5 H 2 C 2 O 4 (aq) + 6 H+ + 2 MnO 4- (aq) 10 CO 2 (g) + 2 Mn 2+ (...
  • Ions From Set 1
    859 words
    Qualitative Analysis of Cations Introduction: The purpose of this experiment is to demonstrate the separation and identification of metal ions based on the insolubility of certain salts. The solubility rules should be taken into account. If a solution dissolves in water, the result contains both cations and anions. Analyzing different ions to discover their nature is the main goal of this experiment. Separation of the cations by testing the differences in solubility of different metal salts is d...
  • Same Electrodes And Salt Solutions
    476 words
    Experiment Aim: To identify the conditions under which a galvanic cell is produced. Equipment: - beakers - copper electrode - filter paper - zinc electrode - electrical wires - copper sulfate - voltmeter - zinc sulfate - sodium nitrate Risk assessment: - Sodium nitrate is poisonous, so gloves must be worn when soaking the filter paper into it. Method: 1. Set up a simple galvanic cell using the equipment listed above and observe the voltage on the voltmeter. 2. Remove the salt bridge and note wha...
