g A. 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

Ocean County College Department of Chemistry Identification of Metallic Ions Purpose: The purpose of this lab exercise was to perform and observe the flame tests of some alkali and alkaline earth metal ions. When electrons in metallic ions are grounded‚ their configuration is stable. In other words‚ the loosely bound electrons in the valence shell of the atom are satisfied at their “low” energy state. They do not require to be balanced by emitting any type of radiation or receiving any

I https://www.oppapers.com/join.php#submit . Experiments with Metals and Ions of Metals Introduction Metals are similar in their physical properties in general‚ but they are not identical. Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability

Determination of Cobalt Oxalate Hydtrate Introduction The objective of this lab is for students to determine the percentage of cobalt oxalate hydrate using the gravimetric analysis. They will also do a redox titration to determine the percentage of oxalate in the compound. After the percentages are calculated‚ you will determine the percent water by the difference of Oxalate and Cobalt from %100. Procedure Determination of Cobalt 1. Weigh 0.3 g of solid cobalt oxalate hydrate (from lab 8) on

exotic fruit and vegetables form developing countries are not reliable. However‚ in my opinion‚ to promote importing exotic fruit and vegetables from developing countries sounds a feasible idea. To begin with‚ the import of exotic fruit and vegetables can diminish the capital used on the study of food. Developed countries usually focus on tertiary industry. Resources devote on researching or technology should always be put on the top priority. Therefore‚ the investigation on exotic fruit and vegetable

purchase of food items etc. This study is concentrated on how people are using the fruits and vegetable waste like peel and skin which are usually thrown to thrash. The result was a surprise because even though some people are throwing the waste to trash‚ many are utilizing it in a different way‚ they are recycling it. In this study‚ few people about 6 out of 20 ( show percentage) are throwing away the waste directly to the thrash which is supported by the study conducted by Parizeau et al (2015)

Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial cross mates homozygous mutant fruit flies with homozygous wild type fruit flies in order to produce

I have taken it upon myself to help improve the amount of fruit that the vineyard produces. One area I noticed that could use improvement was the type of bird netting that was being applied. I personally picked the fruit and saw how much fruit was pierced by birds. I collected data by interviewing managers of the winery‚ and researching online about which practices produced the best outcome. This report analyzes our current bird netting and the procedures that go into it. I also recommend three
