of Vitamin C contained. The concentration of Vitamin C contained of these fruit juices were identified by using titration. Based on the results‚ the concentration of Vitamin C contained in these 3 fruit juices were obtained. The conclusion of the experiment is that different fruit juices contain different concentration of Vitamin C which is important in our daily lives. CHAPTER 1 1.0 INTRODUCTION 1.1 THEORY/LITERATURE Vitamin C is an essential nutrient in humans as it functions as a cofactor in several

Conductor Investigation Experiment LabReport Introduction This experiment is about to test how will the nichrome wire effect the ampere of the electric current. All the possible factor that will effect to the volt of the current • The Length of the wire • The Diameter of the wire • Temperature • Magnetism Aim To determine the effect of the length of the wire on the ampere of the electric current. Hypothesis Nichrome is an alloy(a metal made by combining two or more metallic elements) that is

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the

COORDINATION COMPOUNDS: * FLEXIDENTATE CHARACTER OF POLYDENTATE LIGANDS; * Poly dentate ligands have flexi dentate character in the sense that all donors atoms may not form coordinate bonds with the central metal atom or ion. For example; EDTA which is the hexa dentate ligand also acts as tetra dentate or penta dentate in certain complexes. Similarly sulphate ion‚ which is a bi dentate ligand‚ also acts as a mono dentate ligand in certain complexes‚ e.g. in [Co(SO4)(NH3)5]Cl. * LABILE

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Identifying Organic Compounds 2. Purpose/Problem: I am doing this experiment to find out what kind of organic compounds are in test tubes A‚ B‚ C and D. I am curious to know if substance D was the lipid because it seemed thin and had a slightly yellow tint of color to it. 3. Research: In my research I was informed about facts and appearances of lipids. First of all lipids are non-polar compounds‚ thus they won’t dissolve in water. This is also known as being hydrophobic. They are made with one

Uranium (U) is a metallic‚ silver-gray element that is a member of the actinide series. It is the principle fuel for nuclear reactors‚ but it also is utilized in the production of nuclear weapons. Because uranium is radioactive‚ it is constantly emitting particles and changing into other elements‚ like thorium. Uranium has a well-established radioactive decay chain. U-238 and U-235 (which has 143 neutrons) are the most common isotopes of uranium. Uranium naturally includes all three isotopes (U-238

Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted and towards a stimulus that is favored. Different stimuli which
