Cations And Anion Reaction Lab Essay

Separation and Identification of a Series of Cations Ethan Northcutt BB2 November 2nd, 2016 Abstract Ten cations were reacted with eleven anions and the results of the reactions were recorded; the reactions were performed so that the results could be used in the qualitative analysis of an unknown mixture containing a combination of the same ten cations. There are some distinct differences between the reactions that occurred and the reactions that were predicted to occur. The discrepancies

Name: Lisa Brewer iLab, Week # 2 CATIONS AND ANION LAB Introduction The purpose of this week’s lab is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this, two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure, the product must be precipitated out of the solution and then weighed. For this lab, lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) will be reacted together to demonstrate

LAB 4: ADDITION REACTIONS OF ALKENES: BROMINATION OF (E)-STILBENE (Preparative) Introduction The first purpose of this lab was to predict the stereoisomeric composition of alkenes brominated through electrophilic addition

Introduction This lab revolves around precipitate it reactions. The precipitate reactions happen when it had cations (positive atoms) and anions (negative atoms) in aqueous solutions combined to form an insoluble ionic solid, which is called a participate. In order for these reactions to occur they must be Aqueous and this can be determined by using solubility rules. Predicting these reactions a sign test to find out which ions are present in a solution. Double displacement reactions are the kinds used

Development of an Equation Maggie Purpose: Investigate a chemical reaction using lab procedures and observations. Then, find a pattern of reactivity and explain the findings using a chemical equation and particle diagram. Procedure: Refer to: Department of Chemistry, The Ohio State University. "Development of an Equation." General Chemistry 1210 Laboratory Manual. Vol. 2013-2014. Plymouth: Hayden-McNeil. 32-35. Data/Results: Part A: In the potassium iodide solution, I think there were potassium

Overall this experiment was successful, as it was possible to determine which unknown salt solution the cation belonged too, and also the pairing anion. To figure out the cations, many tests and observations were needed to be made. With the gathered flame test results, and the information given in the procedure, conclusions could be made. Solution A is Sr2+ since it tested crimson red. Solution C is Ba2+ because it tested green. Solution D is Li+ because it turned the flame carmine red. Finally,

the results with other anions from my table of solubilities, and phosphate’s results are the only ones that matched with mine, but sulfate’s did not. This helped me to figure out the known anion. Cation Percipitate Test #3 1. For this percipiate test with my unknown H chemical, I mixed it with , or Copper III nitrate. The purpose of this test was to determine whether my unknown formed a percipitate with this compound, and to eliminate cations. 2. If the reaction with is insoluble, it

Investigating the Determining Characteristics of Cations and Anions  Chem 111 Sec 560  Introduction:  The  purpose  of  this lab was  to study  the specific  characteristics  of cations  and anions,  and  ultimately  to  be  able  to  identify  an  unknown  substance  based  on  our  studies and  tests using the  logic trees  developed through the experiment.  A logic tree  is  a graphical display  of the findings from  this  lab  which,  through  a  series  of  yes/no   questions,  elimination 

for  the unknown anion, when it is added to Ba(No3)2, and AgNo3, it forms a  ppt as well. When HNO3 is added to BaSO4, the ppt disappeared; for the  unknown anion, when HNO3 is added to unknown, the ppt disappeared too,  therefore we can conclude that the unknown is SO42-.  Follow-Up Questions:  1. Devise a sequence of reactions to follow (using filtering or  centrifuging where necessary to remove precipitates) to identify an  unknown containing two or more cations of Group 2 elements
