Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

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

the color of fire? Why do you think each fire burns a different color? The colors of the flames are are due to the different chemicals and substances. The bright yellow-orange of most wood fueled flames is because of the sodium‚ and when it’s heated‚ it emits the glow of the fire. The blue in some wood-fueled flames is because of the carbon and hydrogen emit a blue and purple aura. How are the colors produced by a chemical when it burns related to the atomic structure of the chemical? Colors are

3/5/14 Flame Test Purpose In this experiment I will learn how to perform and observe the flame tests of some alkali and alkaline earth metals and be able to identify and unknown chemical by the color of the flame Procedure I placed about 0.5 mL of 8 different chemicals into 8 different places in the 24-well plate. I then lit the handy wick to keep a flame burning. I soaked a cotton swab in the first chemical and moved the cotton swab in and out of the flame rapidly to see the flame color change.

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings

In The Laboratory‚ the courtesan chooses poison as her murder weapon. Poison is often the weapon of choice for female killers. It requires little or no physical strength to administer‚ and can be done secretly. It also leaves little evidence thus making it difficult to detect the culprit. We believe the act of murder is because of another woman that her lover is with and she feels physically inferior to her rival. We know this because she starts saying ‘What a drop! She’s not little‚ no minion like
