Formula of an Ionic Compound Introduction: The purpose of this lab is to determine the empirical formula of an unknown compound. An empirical formula is a formula that gives the proportions or the kinds of elements present in a compound but not the exact numbers or arrangement of atoms. In this lab, two solutions with equal mouths of reactant ions will be combined; the total volume of the solution will be held constant while the volume ratio of the reactant is varied. The amount if precipitate

Determining the identity of unknown compounds in a given solution is an important skill to have. This can be done through a series of steps including extraction, purification, and spectroscopic methods.1 Chemically active extraction uses the properties of the acid or base to remove it from the solution. The extraction process involves taking the solution, unknown compounds dissolved in organic solvent, and adding basic/acidic solutions to separate the unknown compounds.2 If adding a basic solution, NaOH

grade class began a lesson on compound nouns. We began by playing a matching game. Each child picked a card with a word on it. They then had to try to find a partner who had another word that would pair up with theirs to make a new word. The children were very excited, but no one made the connection with compound words. Once they were paired up, each student said their word and their new word. At this point, they started guessing that we ere going to talk about compound nouns. I observed the children’s

In this study, the unknown compound (No. 55) was obtained, and its identity was determined using three methods: the solubility testing, the melting point analysis, and Thin Layer Chromatography (TLC) method. The solubility testing was used to interpret whether the functional group of the unknown compound was acidic, basic, or neutral. From the study, the unknown compound was dissolved in 1 mL of water, 3M HCl, 3M NaOH, and 5% NaHCO3. First, the unknown compound was insoluble in water, so it was

Inorganic and organic compounds are both necessary for the human body. The definition of an inorganic compound is a compound that does not contain hydrocarbon groups. An inorganic compound is composed of several other elements, such as salts, metals, and other elemental compounds, but can contain hydrogen or carbon. If they have both, carbon and hydrogen molecules, they are organic. Organic compounds are defined as compounds containing hydrocarbon groups. Organic compounds will include things like

INTRODUCTION In this experiment, the identity of an unknown compound will be deduced from analysis of physical properties, boiling points, IR spectra, chemical tests, and melting points of derivatives. This experiment allows for individual selection of chemical tests, order of steps, and additional analysis, as necessary, based on what is needed to determine identity of unknown. DATA physical state: _____Liquid________________________________________ viscosity: ____ slightly thick consistency___________________________

Introduction The concept of compound interest has been around since early times of humanity, unofficially. This is due to lack of documentation and dating back to when agriculture was practiced by tribes and early civilizations. In the late 14th century, Italian mathematician were the first to use compound interest on record. By the 17th century, most financial institutions were using compound interest. However, problems began to arise with compound interest causing a need for simplification

The guiding question of this ADI lab was, “What are the identities of the unknown compounds?” The goal of this lab was to understand the relationships between moles and molar mass to find the identity of unknown compounds. The mole can be used to measure small amounts of a substance or is used to convert from unit to unit using dimensional analysis. One mole is equivalent to the molar mass in grams of that substance. If you start with the moles of an unknown substance, multiply it by a given compound’s

Even though the compounds provided in this lab did not come with any information, one must use their knowledge and investigative skills to formulate their own justifications for the unknown substances through performing a wide variety of tests. To elaborate, these trials are crucial for solving the identity of these compounds as each of their characteristics that they exhibit (the outcome of the experiments) are directly connected to a specific chemical compound group, whether it be metallic, ionic

Identification of Unknown Organic Compounds by Melting Point, Boiling Point, Infrared and Nuclear Magnetic Resonance Spectroscopy Background and Method In the previous labs we were experimenting with different methods so that we can find different physical properties of the known compound. However, this lab report is a little different as it gives us two unknown compounds where we have to use the prior knowledge we have gotten in the other labs to ensure that we know exactly how to ultimately
