An Introduction to Qualitative Analysis Purpose: Tests the ions of Mg2+‚ Ca2+‚ Sr2+‚ and Ba2+‚ and identify them separately. By using these observations‚ identify the unknown ion. Then tests the ions of SO42-‚ CO32-‚ Cl-‚ and I-‚identify them separately‚ and use the observation to identify the unknown. Procedure Part I - Qualitative Analysis of Group 2 Elements Mix 0.02M K2CrO4 with each Mg(NO3)2‚ Ca(NO3)2‚ Sr(NO3)2 and Ba(NO3)2 together. Secondly‚ mix 0.1M (NH4)2C2O4 instead

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far

Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion

Question1 Quantitative data are measures of values or counts and are expressed as numbers (www.abs.gov.au). In other words‚ quantitative data are data about numeric variables (www.abs.gov.au). Four types of quantitative data are interval‚ nominal‚ ordinal and ratio. Firstly‚ interval scales are numeric scales in which we know not only the order‚ but also the exact differences between the values (www.mymarketresearchmethods.com). Other than that‚ interval data also sometimes called integer is measured

There are several ways to determine where the word boundaries of spoken language should be placed: Potential pause: A speaker is told to repeat a given sentence slowly‚ allowing for pauses. The speaker will tend to insert pauses at the word boundaries. However‚ this method is not foolproof: the speaker
