Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is also

Fernandez 3.06: Lab and Guided Lab Report Part I: Prelab Research the answers to the following questions on the internet‚ and write your answers in your own words. For each answer‚ include the address of the website (or title and author of a book or article) that you used to help you answer the question. 1. Which type of compound usually has higher melting points‚ ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds usually have

In this lab‚ theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds

Covalent Compound: Cocaine Cocaine‚ also known as coke‚ is a covalent compound‚ which are molecules that consist of groups of atoms held together by covalent or coordinate bonds. In the United States cocaine is an illegal drug because of the harm it does to a human’s body. It has been used for many years for many different reasons by many different people. Cocaine and it’s leaves‚ which are found on the plant of the Erythroxylen coca (cocaine.org)‚ originated by the South American Indians who have

Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

In this lab‚ each person in the group will have two pennies. Galvanization of a penny will create a brass penny. Galvanizing the penny in sodium hydroxide with zinc causes the penny to turn from bronze to silver. Once the penny is fully galvanized you will burn the penny and spray it off and then it will turn gold. There will be a weight change also a mass change. Observing the penny to see it turn from bronze to silver to gold. Literature review Covalent bonding is a bond when atoms share pairs

4/29/2013 5.1 Lab Report - Identification of Metallic Ions TITLE: LAB 5.1 IDENTIFICATION OF METALLIC IONS PURPOSE: In this lab we are learning how to observe and perform “flame tests”‚ of alkali and alkaline earth metal ions. We will use basic lab equipment provided in our Labpaq‚ and follow all safety precautions in this lab. From reading the discussion and review‚ we understand that the normal configuration of the electrons is called “the ground state”. We understand that they are

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
