Cations and Anions Reaction Introduction: This experiment seeks to explore different chemical reactions conducted in the lab. A cation is defined as positively charged ions‚ which are K+ and Pb2+ in this experiment‚ and an anion is termed as negatively charged ions‚ which are CrO4 2- and NO3 2-. The major objective of this lab experiment was to examine the reaction between cations and anions‚ as well as observing‚ and documenting the chemical reactions. We will be demonstrating the reaction between

Testing for Cation and Anions OBJECTIVE: • Determine the presence of a cation or anion by a chemical reaction • Determine the cation and anion in an unknown solution All salt solutions have both positive (Cations) and negative (Anions) ions dissolved in it. In this experiment you will observe chemical reactions to determine the presence of specific anions and cations. Compare your observations with the reactions of the known solutions and the unknown solution to determine the ions present

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Alkaline Phosphatase was isolated using various techniques. BCIP spot test was performed after the anion exchange chromatography was done and the fractions were collected. The picture of BCIP spot test of the 20 fractions can be seen in figure 1. The intensity of each spot was different from each other. The more intense color the spot was‚ the more concentrate the AP was. The fractions were chosen to combine together based on the intensity‚ which made the stage 4 enzyme. Different volumes in each

Ashley Huston ILab‚ Week #2 CATIONS AND ANION LAB Introduction The purpose of this lab is to demonstrate a double-replacement reaction of ionic compounds. In this experiment‚ you will combine two ionic compounds. Both compounds are soluble in water. If a response happens between these two compounds‚ then a precipitate will form because one of the two resultant compounds is not soluble in water. This is a hint that a reaction took place. Cations are positively charged ions that are attracted

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that
