1. The objective of the investigation is to determine what types of ions are found within various solutions. Chemical tests were used to see if there were any changes in the solutions and if there were, we would know what ion was in the solution based on the reagent which was mixed.

2. Although, in this lab I only noticed two changes which resulted in a positive test result. The changes were color change and precipitation forming in the solution. For example, well water changed color after mixing potassium thiocynate and it indicated there were potassium ions in well water. Precipitation formed in the solution when potassium chloride was mixed with silver nitrate and indicated there were chloride ions in silver nitrate and it resulted in chemical change.

    Identifying Ionic Compunds Lab

    In this investigation, the student is to identify the ionic compound in a solution from a list of possible compounds given solutions of all the possible compounds. The student needs to find the reactions in between each solution including the reactions with the unknown solution #1. The colors of each solution will help to determine if the solution reacting with the unknown #1 is the same as the unknown and the different colors of the solutions are qualitative data. The reactions between each combination of solutions were also qualitative data and helped determine the unknown solution. If there was a reaction between one of the 8 solutions and the unknown solution #1, then the solution could not be the unknown. The student shall also discover how ionic compounds react physically and chemically to form one ionic compound. The students will also discover how to balance chemical equations to represent chemical reactions.…

    Detection of Ions in Solutions Using Acid/Base Chemistry: A Quality Control Test

    Objective: This lab focuses on the detection of ions using titration as an analysis tool. You will standardize NaOH and HCl solutions so that you know the exact concentration and then prepare samples of common household items in order to determine the amount of calcium in Tang®, Mg(OH)2 in Milk of Magnesia, etc. You will learn to prepare samples of a specified concentration, learn about acids and bases through the use of titrations and learn how to detect endpoints using different indicators. You will become adept at measuring pH with both a pH meter and indicator paper. You will then conduct quality control testers and determine if the label on a bottle of over-the-counter product actually contains the percentage of compound that it advertises.…

    Aqueous Reagents Lab

    Introduction: A solution is as a homogeneous mixture containing two or more substances. Reagents are added to solutions to create a chemical reaction or added to see if anything occurs. Reagents can be added to solutions to see if there is a presence of other substances. For example, iodine added to a lead solution. Iodine would be the reagent and would cause a chemical reaction confirming the presence of lead. We use a qualitative chemical analysis to identify elements present in the solutions, in this case, adding a reagent. A quantitative chemical analysis is used to determine the percentage of a substance in the solutions. Solvation is the process of the attraction between…

    Identifying Ionic Compounds

    In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate, a dropper, and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color, texture and solubility changed because of the properties that came from the other solution.…

    I found it really interesting that there were not very many changes to the substance. I really thought that almost all of them would change or have some kind of with the addition of HCl. I was really surprised that most of the substances remained unchanged. The ones that did change happen instantly when another condition was added to the test tube. The HCl was the chemical that changed the substances the most is the main observation that I saw.…

    Ion Exchange Chromatography

    Ion Exchange Chromatography

    Ion exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net charge. Ion Exchange Chromatography relies on charge-charge interactions between the proteins in your sample and the charges immobilized on the resin of your choice. Ion exchange chromatography can be subdivided into cation exchange chromatography, in which positively charged ions bind to a negatively charged resin; and anion exchange chromatography, in which the binding ions are negative, and the immobilized functional group is positive. Once the solutes are bound, the column is washed to equilibrate it in your starting buffer, which should be of low ionic strength, and then the bound molecules are eluted off using a gradient of a second buffer which steadily increases the ionic strength of the eluent solution. Alternatively, the pH of the eluent buffer can be modified as to give your protein or the matrix a charge at which they will not interact and your molecule of interest elutes from the resin.…

    Ions in Our Daily Life

    An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution, when an electric field is applied. It is from Greek ιον, meaning "going." The word ion also is responsible for electrical current being symbolized by the letter i in chemistry and physics.…

    Analytical Chemistry

    Redox Titrations are among the most important types of analyses performed in many areas of application, for example, in food analysis, industrial analysis, and pharmaceutical analysis. Tiration of sulfite in wine using iodine is a common example. Alcohol can be determined by reacting with potassium dichromate. Examples in clinical laboratories are rare, since most analyses are for traces, yet these titrations are still extremely useful for standardizing reagents. Iodine is a moderately, strong oxidizing agent that can be used to titrate fairly strong reducing agents. Titrations with I2 are called Iodimetric Methods. In iodimetry , the titrant is I2 and the analyte is a reducing agent. The end point is detected by the appearance of the blue starch-iodine color. Iodimetric titrations are usually performed in neutral or mildly alkaline (pH 8) to weakly acid solutions. If the pH is too alkaline, I2 will disproportionate to hypoiodite and iodide: I2  2OH -  IO-  I-  H 2 O On the other hand, there are three reasons for keeping the solution from becoming strongly acidic. First, the starch used for the detection of the end point is a carbohydrate which tends to hydrolyze or decompose in strongly acidic media, thus effecting the end point. Secondly, the reducing power of several reducing agents is increased in neutral solution. The last reason for avoiding acid solutions is that the I  produced…
