1 Professor Tolentino Maria Oyervide EXPERIMENT #4 IONIC AND COVALENT COMPOUNDS Abstract: This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. There were four unknown solutes A‚ B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. Covalent compounds are made up of molecules which are electrically neutral. Ionic compounds are composed of ions‚ which are positively

The purpose of this experiment was to observe the hypothesized correlation between ionic strength and degree of ionization of a weak acid‚ while determining the factors that would impact the degree of ionization using measurements of pH. It was initially required to prepare standard 20-mL solutions of varying concentration of acetic acid for use in the rest of the experiment. One solution of CH3COOH was supposedly developed to be 2.00M‚ however it is highly possible that the solutions of CH3COOH

Atoms and Ions By observing whether reactions occur between solid metals and metal ions in solution‚ you can determine the order of oxidizing and reducing agents according to strength. Question How can the presence or absence of a reaction provide information about the relative strength of oxidizing and reducing agents? Safety Precautions • Wear goggles‚ gloves‚ and an apron for all parts of this investigation. • If you spill any solution on your skin‚ wash it off with large amounts

Solubility as a Property of Matter A Lab of Chemicals‚ Chromatography‚ and Crime! Chemistry is a natural science that deals with the composition of matter and the changes it undergoes. At crime scenes‚ investigators often find unknown materials that need to be identified. If an unknown material is a mixture‚ an investigator may want to know one or two things about it: What are the ingredients of the mixture? Is the mixture found at the scene the same as a known mixture? A mixture is a collection

compound. We accomplished this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric

Hoang Stewart Dahlberg IBO 58001 February 4‚ 2014 There are significant differences between rule of law and rule of man. First‚ rule of law is a system which is operated based on the law. The government‚ officials‚ or individuals are uncountable under the law. The laws must be specific‚ stable and are applied fairly to everyone. While rule of man is a system that one person or a small group of people rule the country. A society that one man has absolute authority and stay out of any law. He is free

Introduction Part 1: The purpose of this experiment was to determine the quantity of water in several different types of popcorn. Determining the amount of water in the product will determine the likelihood of it popping. More water in a piece of popcorn increases the amount of pressure buildup when it is heated. With the data it will be determined if more expensive popcorn equates to a better‚ more reliable popcorn. Part 2: The purpose of this experiment was to create a method of separating a mixture
