These have been provided as a MS-word. You will be directed to use a website to complete an online simulation of the qualitative analysis experiment. General Background to Qualitative Analysis Experiment Qualitative analysis is a method used for identification of ions or compounds in a sample.

In many cases, qualitative analysis will also involve the separation of ions or compounds in a mixture. Examples of qualitative tests would include ion precipitation reactions solubility tests or chemical reactivity tests.

The separation of ions is easily achieved by taking advantage of their solubility properties. In a lab simulation, you will use selective precipitation, which takes advantage of the differing solubility of these ions in different conditions, to separate these ions from the mixture and then confirm their presence or absence using selective chemical reactions.

In the first part of the experiment you will use a qualitative analysis scheme with known solutions containing one or more of the group I cations to show how the ions behave and can be identified. Note that the separation procedure we will use in the online lab simulation is generally similar to that described in this paper. However, the details of the confirmations are different and are described in the online lab simulation documentation see below. Part C of these instructions qualitative analysis cations information on how to use the online lab simulation.

Part D of these instructions describes the experiments you should carry out. Part E contains instructions on postlab questions and how to submit your lab assignment.

Instructions for Online Qualitative Analysis Simulation. It was created by Prof. A new page will open that contains a description of the experiment qualitative analysis cations and a suggested experiment to use known solutions. It is a good idea to print this page if you can so that you can refer to it at any time. Watch the powerpoint presentation found in the lab assignment. Qualitative analysis cations this I will show you a run through of how the online QA lab simulation works. General: Make notes and observations as you perform procedures with the simulation. Use to clear the simulation between experiments.

Once you have this mixture, carry out the procedure described in the flow sheet see also powerpoint presentation to separate and confirm the presence of all three ions in this mixture. Make careful notes of what you do and note down what you observe at each step. This trial unknown contains one or more the group I cations randomly selected by the simulation. Carry out the same procedure that you did before for a mixture of known group I cations Experiment 2. You can repeat this analysis of a trial unknown as many times as you like to practice. A new sample will be created each time you select a trial unknown. Experiment 4 — Analysis of an assigned unknown: For your fourth experiment, you will analyze an assigned unknown that contains qualitative analysis cations or more the group I cations.

I will assign you a specific assigned unknown identified by a https://modernalternativemama.com/wp-content/custom/essay-service/dissertation-assistance-writing.php from — ]
