Qualitative analysis is a method in analytical chemistry which involves the identifying of unknowns in a given solution. It is important in chemistry especially when one is dealing with unknown mixtures to be able to establish the solution properties and the methods of separation if you need to separate. In the general Laboratory set up, qualitative analysis is aimed at getting a deeper understanding of the cations and also learns how to handle them and detect them effectively when in any solution.
The main hypothetical question in qualitative analysis is whether a certain cation is present in a given solution. To prove that hypothesis null, then a series of chemical reactions are conducted and the color changes are mainly used to establish their presence. It should be noted that many cations will have similar color changes and so a series of subsequent reactions are used in the detection of a certain cation (Page & Foster 11).
In this lab we divided the cations to be characterized into two sub groups, this was done by selective precipitation. The precipitate was then separated physically be centrifuging as it settles out and the supernatant liquid decanted. This was the first step where the large group was separated into smaller groups so that a definitive test can be performed to verify the presence or absence of a specific cation. The cations were classified into two groups according to their ability to dissolve. Group A had ( Bi+3, Fe+3 and Mn+2) while group B had (Al+3, Cr+3 and Sn+4) which were to be used in the two labs. The ions were in a combined unknown solution and they were to be analyzed to establish the cations present. To be sure where any of the cations was present in the solution it was important to run a number of procedures that are described below.
In test 1, Mn+2 ions were confirmed present. In the addition of NaBiO3 the color of ...Download file to see next pagesRead More

Mann is establishing whether the moment of passing the title of property from the seller to the buyer depends of the transmission of the title certificate. The Court has to explain if nondelivery of the certificate means nondelivery of title of care. Under the Wisconsin counterpart of N.Y.U.C.C. § 2-401 (2) “Unless otherwise explicitly agreed title passes to the buyer at the time and place at which the seller completes his performance with reference to the physical delivery of the goods, despite any reservation of a security interest and even though a document of title is to be delivered at a different time or place…”1...

Analysis of Respiratory Physiology
... Analysis of Respiratory Physiology Abstract The respiratory physiology has an important role in human life. Its study therefore is very important. In light of this significance three experiments which are discussed in this report were conducted in order to assess the factors which affect the respiratory rate and interpret the findings and compare them. Vital capacity of male and female was compared and the effect of partial pressure of carbon dioxide in the inspired air along with the effect of hyperventilation on breath holding limit was also measured. Carbon dioxide is one of those factors whose presence in the inspired air directly relates to the respiratory rate and tidal volume. Along with carbon dioxide there are...

Volumetric Analysis
...AIM: To determine the percentage of iron (II) and iron (III) in a mixture containing both, using volumetric procedure. Introduction: Volumetric Analysis is a means of finding the concentrations of a solution. This is done using a method called titration. A standard solution, this is the solution of a compound of accurately known concentration that reacts with the substance to be analysed. The test solution is the substance to be analysed, which has an unknown concentration. Means of detecting the end point of the reaction between the standard and test solutions. Usually an indicator is used however in redox titrations, the oxidising agents are self indicators which means an indicator is not needed. As soon as the...
