Metallic ions lab report

Safety goggles for eye protection are recommended and lab coats are There are several types of titration methods in chemistry. First, the electron can absorb a photon of just the right amount of energy to move it from one quantum shell to another. I placed the following solutions in the following locations: The Flame Test lab was an in-class lab where we tested chemicals in the flames to see the wide range of colors in the color spectrum.

We will perform a flame test on several metallic ions and observe their flame color in order to confirm its identity. The amount of energy in the photon determines its color; red for the lowest energy of visible light, increasing energy through the rainbow of orange, yellow, green, blue, indigo, and finally violet for the highest energy of visible Metallic ions lab report.

It will appear to be one color, which we will carefully describe. The Flame Test lab was Metallic ions lab report in several parts. What color of light has the lowest frequency? In this experiment we saw a range of colors from dark pinkish red to dark purple, possible violet.

Electrons in excited states do not usually stay in them for very long. I enjoyed this experiment and although I am still a bit uneasy dealing with heating substances,I am getting more comfortable in doing so.

This can happen in two ways. How are electrons "excited"? I noted this in my lab packet and I proceed with the above same steps with the remaining solutions and noted all of my results in my Table 5. Submit your answers to these questions on a separate sheet of paper if more room is needed before you begin the lab.

Ammonium hydroxide was then titrated slowly into the conical flask and the conical flask was swirled gently to ensure the reaction is We can view the emission spectrum of colors all at once with the naked eye.

Violet has the highest amount of visible light energy.

When electrons lose their energy they do so by emitting a photon of light. This is a replication of the article used in the pre lab: Identify unknown metallic ions by means of its flame test.

Therefore, it is important to follow the safety rules outlined in this lab manual. The first one that I will focus on is the Pre Lab questions: You should assume that all compounds encountered in the laboratory are toxic and handle them accordingly.

Inorganic Chemistry Transition elements contain ions that present in aqueous solution as complex ions. This technique of using certain chemical compounds to color flames is widely used in pyrotechnics to produce the range of colors seen in a fireworks display.

What color of light has the highest frequency? The only one that was not a Alkali or Alkaline Earth metal with non-metal was the Cupric Nitrate which is still a metal, but is located in the transition element region of the periodic table.

Second, when atoms are heated their electrons can gain energy from the heat. What color of light is the lowest in energy? When the compound to be studied is excited by heating it in a flame, the metal ions will begin to emit light.

After moving a little quicker back and forth I noted that the flame turned a yellowish to a pale orangish color.

Firstly, is the acid-base titration method which was carried out during this experiment. Since the question pointed out spilled into the fire, this would most likely be the best guess. In this lab, we will record the flame test color of several metals by making solutions of salts, or ionic compounds, of those metals then igniting them with a match.

Their energy is directly proportional to the frequency of the light remember: Sometimes they can be promoted to a higher-energy electron shell. Introduction to the Flame Test Lab: Based on the emission spectrum of the element, the compound will turn the flame a characteristic color.

They then return to their ground state by emitting a photon of light the law of conservation of energy indicates that the photon emitted will contain the same amount of energy as that absorbed in the quantum jump.A number of common metallic elements emit light strongly in the visible region, If we examine the emission spectra of these ions with a spectroscope, we find that as with mercury and Flame Tests & Electron Configuration REPORT FORM Name _____ Instructor _____.
