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

Then‚ measured 25cm with the meter ruler to make a point and placed some blue-tac on it 3. Also repeated the points for distance of 50cm‚ 75cm and 100cm 4. Then the ball was placed at the starting point 5. After that‚ the ball was released while

Aseel Muqbel 15/2/2015 11th D Flame Test Intro: The flame test is a procedure used by chemists to identify the presence of specified metal ions‚ based on the color the flame that appears along with it when it ’s heated. Our flame test was in lab class‚ where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced‚ the second one was to identify unknown metals based

Boake‚ Hannah Harper Various Color of Light as the Effect of Electron Emission Objective Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests. Background When atoms absorb energy‚ electrons move into higher energy levels‚ and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light

Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab‚ the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum‚ which one can use to identify them. For example‚ NaCl was highlighter yellow‚ Sr(NO3)2 was sun orange‚ CuCl2 was turquoise‚ LiCl was neon red‚ KCl was solar flare yellow‚ and BaCl2 was Voldemort green. Introduction- In Bohr’s

urpose: The purpose of this lab is to determine the impact of light on the germination of seeds Research: A seed is the reproductive unit of a plant that contains a mature ovule with an embryo. The seed is made up of the seed coat hard shell over the seed‚ two cotyledons‚ fleshy membranes that store food‚ an epicotyl‚ which forms the primary shoot‚ the radicle‚ the primary root of the seed‚ and the hypocotyl‚ the stem of the epicotyl. When the seed is triggered by water to sprout‚ a process called

TA: Michelle Lamont Medieval Science Lab Report Introduction Medieval and early renaissance scholars believed in three scientific paradigms: alchemy‚ astrology‚ and folk belief. These three scientific paradigms are produced without extremely thorough testing‚ yet they still can produce accurate predictions. This means that the medieval science not only allowed beginning with scientific method‚ but also beginning with superstition and theories. One of the three

This lab tests the process of germination with various pH levels. The pH level of something is its measure of acidity or how basic it is‚ solutions with a pH of less than 7 are said to be acidic‚ and solutions with a pH greater than 7 are said to be basic. The tap water that was used to water our beans had a pH of 6. In this lab‚ we studied the process of germination (the process by which a plant grows from a seed). Certain environmental factors can cause or stop a seed’s germination‚ and these factors

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 and
