Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

Unit 2: Lab 1: Cost of different cloud services: Amazon: Has a price range of $0.060 per hour on a Linux based system and goes up to $0.155 per hour for a Windows with SQL and Web system. You can purchase a per year upfront cost or stay at a monthly cost. Google: Offers you two pricing options‚ $5 per user per month or $10 per user per month. The $5 option does not give you any archiving‚ data retrieval or data discovery and export options. Where the $10 a month per user has those options.

Introduction In this lab‚ the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead‚ along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then‚ the beads

Week 2 Lab #2 Assessment Questions 1. Privacy is where a person has control their own personal data Privacy is the individual’s right to control‚ the person has the opportunity to assess a situation and determine how’s it’s used. Just because information is secure it doesn’t mean it is secure. 2. In 2002 he received permission to obtain a laptop and hard drive not to acquire the data. 3. Possible consequences might be that personal information being used against the people in the VA system

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

Two metal bars of an unknown identity were obtained‚ each bar was understood to have varying masses and volumes. The metal bars were then measured for their masses‚ bar one was measured at 19.3221g and bar 2 was measured at 15.6225g respectively. A graduated cylinder of 10 or 25 milliliters was obtained‚ in our testings‚ the 10 milliliters was used. Water was introduced into the graduated cylinder and the initial volume recorded at 4.9mL for bar one‚ and for bar two the cylinder was recorded to have

permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly. c) The reaction does not have any side reaction
