properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness‚ safety and potential yield of the compound. So to be more specific

Identifying Ionic Compounds Written by Ashleigh Lara. In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate‚ a dropper‚ and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color‚ texture and solubility

is an atom or a molecule with a positive or a negative charge due to the loss or gain of one or more electrons. Ionic solids are salts (such as NaCl) that are held together by a strong force of attraction between ions of opposite charge. Molecules are the smallest physical units of an element or a (chemical) compound. Ionic solids are also known as salts because salts are ionic compounds that are formed from a reaction between an acid and a base. Hydrates are inorganic salts which contain specific

Coordination Compounds are compounds that contain at least one complex ion. Complex ion is an ionic species consisting of a metal ion bounded one or more Lewis bases. Coordination complex is the product of a Lewis acid-base reaction in which neutral molecules bond to a central metal atom by coordinate covalent bonds. A coordinate covalent bond is a covalent bond in which one atom supplies both electrons. Ligands are atoms or molecules with electron pairs available‚ and they may be neutral or negatively

CHEM111AC‚ Experiment#9 - Ionic Reactions Discussion/Error Analysis In the first part of this experiment‚ the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another. For solution A: mixing A + B formed a precipitate‚ A + C generated heat‚ A + D gave no reaction‚ A + E gave no reaction‚ A + F gave no reaction‚ A + G formed a precipitate. For solution B: mixing

Lab Techniques & Measurements Pre Lab Questions: (4pts) 1. What will you learn after completing the lab? -The experiment will introduce different level of precision and measuring to the appropriate decimal place and will be familiar with measurements and weight. 2. Write the symbols and equation used to make a dilute solution from concentrated or stock solution. - The concentration of substance is described as molarity and this can be expressed as – Molarity

How do ionic compounds form? How do electrons change the shape of a molecule? These are just a couple of the questions that this paper will answer. How do ionic compounds form? Ionic compounds are formed by positive and negative ions. An ionic bond means that there are valence electrons being shared between the two molecules. This can cause the molecule to become negative or positively charged. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the

Identifying Organic Compounds Joe Harris 11/12/07 1. Background Organic compounds are‚ by definition‚ any chemical compound containing carbon. These compounds include carbohydrates‚ polysaccharides‚ lipids‚ proteins‚ and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the

thousands of compounds which have been discovered‚ and are yet to be discovered‚ with all these possible combinations it is necessary to provide order through a systematic naming system. This naming system‚ aside from organization also provides the reader with information about the given element. There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary ionic compounds
