PROJECT IN CHEM LAB. Submitted by: BHEA MARIE MENDOZA Submitted to: -CATIONS and ANIONS- Cations are positive charged ions. A cation has fewer electrons than protons. Anions are negatively charged ions. An anion has more electron than protons. The nature and magnitude of charge on ion depend on the position of an element in the periodic table. In forming an ion‚ an atom of a main group element loses gains electrons to obtain the electronic configuration of the noble gas

In this practical the aim was to determine the concentration of Na2CO3 in a standard solution‚ by using Hydrochloric acid to neutralise it. This experiment involved using distilled water to dissolve the sodium carbonate until 250 ml of solution were made. I had to calculate‚ from the information provided‚ how much sodium carbonate to use in the making of the solution. Using the volume and concentration of the solution‚ I was able to calculate the moles of the solution (concentration x volume). Using

High Performance Liquid Chromatography Analysis of Aspirin Problem: Was aspirin (acetylsalicylic acid) successfully synthesized? Are there impurities or by-products present in the synthesized aspirin? How pure is the synthesized aspirin? Introduction: In the last experiment‚ aspirin was synthesized followed by characterization of the product using several different techniques. Melting point was a test that provided information about the identity and purity of the aspirin product. The iron(III)chloride

TITLE: Determination of Riboflavin by using UV-Vis spectrophotometry. ABSTRACT: The amount of Riboflavin in various brand of children multivitamins was determine by using UV-Vis spectroscopy instrument‚ the series of standard of riboflavin was prepared in order to determine the amount of the riboflavin in the sample of children multivitamins. The maximum amount of riboflavin was found in the Champs multivitamin that contains 0.1155 mg followed by Chewies 0.1131 mg and Scott’s 0.0672 mg. OBJECTIVES:

compressor and the pressure‚ represented by the air flow‚ the power output and the efficiencies are also plotted. From the graphs we can see that the discharge pressure‚ isothermal efficiency‚ T and isentropic efficiency‚ S increases whereas the volumetric efficiency and vol decreases. The errors will be discussed later. INTRODUCTION: Two-stage air compressors are used in a range of industries‚ such as in the manufacture of chemicals and fertilizers. They supply power to pneumatic
