Date: 20/03/13 Flame Test – Investigating Compounds Aims To identify the presence of a relatively small amount (ie low concentration) of a metal ion in a compound. Method 1. Clean a platinum or nichrome wire by dipping it into concentrated hydrochloric acid. 2. Hold the platinum or nichrome wire at the hottest or blue part of a non-luminous Bunsen flame. 3. Repeat until the wire does not produce any colour in the flame (note: do not touch the wire‚ as salt in sweat will produce

Lab 1: Flame Test 11 Chemistry‚ university Preparation Conducted: September 20th‚ 2010 Purpose: To observe‚ and create a chart of the colours produced when solutions of known metal compounds are heated to high temperature. Question: What colours are produced when different metallic compounds are placed in a flame‚ and why this happens? Hypothesis/Prediction: Different salts will produce different colours when placed in a flame‚ due to the fact that each element has a different

Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If the color of one of the unknown elements

Corn is often thought of as a food but in fact ‚ the bulk of corn that’s produced today does not go to food production. We use corn as an alternative in many things‚ such as plastic ‚ medicine‚ batteries etc. Its amazing how we can use corn not just as a food but also in many different things. Corn syrup is used in a lot of foods now a days. Corn syrup is almost

When I think about my everyday life and what each day consists of‚ I cant think of anything else but getting up early‚ going to school‚ going to work‚ coming home doing home work and going to sleep to get up the next day and repeat this cycle over again. I’m a college student which males me a lot like everyone else in this class thus makes my everyday routine very much similar to all of yours. School and work life is something most of us share‚ but what we choose to do on our free time is

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

ACTIVITY FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests

Students will use both functions to predict the future global population‚ provided the current growth rate or 1.3% (Abbott‚ 2004). This relation will also be used to find out how long it will take the global population to reach a certain level.

found in a compound. And in order to detect the presence of metals in a compound‚ flame test is done. The result of the flame test is based on each element’s characteristic which is emission spectrum. Flame test involves placing a sample of an element or compound in a non-luminous flame and observing the resulting color of the flame. Flame test is fast and easy to perform. All the equipment needed for flame test is present in all chemistry laboratories. Solubility is a quantitative term defined
