Qualitative Test for Some Cations I (The Silver Group) Objective: At the end of the class the student should be able to: 1. Separate‚ detect and identify the ions in a given unknown solution possibly containing the ions of the silver group. 2. Identify the substance responsible for the positive result of each test 3. Point out the suitable conditions necessary for the detection process and the reasons for such conditions Introduction Procedure: 1. 3 test tube labeled 1‚2‚3 was obtained

Observing a Single Chemical Reaction Qualitative vs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. The results of the experiments were determined through close examination and observation of both qualitative and quantitative elements of the changes that occurred when a blue crystal‚ Copper Chloride‚ reacted with aluminum

Qualitative Analysis Qualitative is where the results give a colour that you have to match up to a colour chart‚ or have you have done to see if it is positive or negative with a description of what a positive reaction should look like. This test is less reliable as some colour or positive reaction look similar to each other or the same but by adding different chemicals. An example of qualitative would be a pH test as the result gives you a colour and then you have to match it up to the pH scale

PROJECT IN CHEM LAB. Submitted by: BHEA MARIE MENDOZA Submitted to: -CATIONS and ANIONS- Cations are positive charged ions. A cation has fewer electrons than protons. Anions are negatively charged ions. An anion has more electron than protons. The nature and magnitude of charge on ion depend on the position of an element in the periodic table. In forming an ion‚ an atom of a main group element loses gains electrons to obtain the electronic configuration of the noble gas

Determining substances contained in a mixture using qualitative analysis Introduction: The purpose of this lab was to determine the substances contained in a random mixture using qualitative analysis. Qualitative analysis is the analysis of a substance in order to ascertain the nature of its chemical constituents (Qualitative analysis). The substances that could be found were iron‚ cinnamon‚ corn starch‚ baby powder‚ copper‚ and strontium. A magnetism test was used to determine whether iron or
