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

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 morning to the books we read at night ‚ corn is in nearly every aspect of our lives. 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 exactly as sweet as the granulated sugar

Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the

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

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.

Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The unknown element color will be

Math‚ and specifically Algebra‚ is used every day in people’s lives. Explain why you agree or disagree with that statement and provide examples to justify your stance. Include a useful example with numbers to support your claims. Yes‚ I do agree we use math and sometimes algebra everyday. For example‚ math which we use for the grocery store‚ shopping‚ paying bills‚ purchasing items and taxes. As a matter of fact whenever you have to buy‚ sell‚ or trade you’re using math or algebra in some kind

CONCLUSION After many class lab days‚ I concluded my unknown was Calcium Carbonate due to results from the Flame Test and Anion I Test. Throughout our lab days‚ my friends would help me determine various odors and colors of the substances which allowed me to confirm my answer. Also‚ I looked select test results up on the internet to see if they matched my observations. On our first lab day‚ I received my bottle and noticed a white precipitate in the bottom therefore‚ my unknown was insoluble. I
