Click on the link below or copy and paste it into your browser. It is ordered from most reactive element to least reactive element.
Aluminum is the reducing agent, and chlorine is the oxidizing agent. Compare your answer to question 3 with the activity series. Net ionic equations remove spectator ions from the chemical equations. When an atom gains electrons, it is reduced. Oxidation occurs when an element loses electrons, becoming a cation, or positively charged ion. Place the ribbon in each row well that contains solution. First, the reactivity of the metals is determined by reacting a series of metals with metal salt solutions.
Nitrogen is the reducing agent, and oxygen is the oxidizing agent. After adding one piece of one metal to each of the test tubes containing solutions and noting any observed changes, empty and rinse the test tubes. Background: The usefulness of metals in structural and other applications depends on their physical and chemical properties. When an atom loses its electrons, it is oxidized. Data from Table 2 was collected by obtaining a solution of metal ions and dropping in a piece of metal. Valence electrons determine the charge of the ion and the ionization energy quantity.
In each of the following oxidation-reduction reactions, substances are oxidized and reduced by oxidizing and reducing agents. The periodic table was developed in the 1860s by Dmitri Mendeleev. It was expected that the element at the bottom of the activity series would not react with any of the other metals. Let's place various metals into solutions of metal ions and into a solution of hydrochloric acid. Only reactions that occurred are listed below.
You need this equipment: 7 small test tubes, test tube rack You need these materials: 0. Post-lab questions: Calcium should be the most reactive with water. Calcium was the most easily oxidized, while copper was least reactive. Two important terms for our experiment are oxidation and reduction. It is also possible that a color change occurred upon the metals in the solutions that some researchers noticed that others did not. Which of the metals reacted with the fewest solutions? Activity Series Showing top 8 worksheets in the category - Activity Series.
Some of the worksheets displayed are Work 4 single replacement reactions step 1, Activity series work answer key, The activity series for single displacement reactions, Chemistry single replacement reaction work, Chemistry single replacement reaction work, Activity series of metals 1, Two activity series metals and halogens, Arithmetic series date period. This is a lab report for my General Chemistry class. Zinc was somewhat reactive, reacting with one solution. Objective: -To explore the reactivity of metals -To practice writing single replacement reactions -To practice using the activity series chart in your reference table Procedure: 1. In some combinations, a reaction occurred, and in other combinations, a reaction did not occur. The activity series is a list of the metals in order of ease of reaction, or the ability of the element to give up electrons.
For example, gas formations, bubbles, fizzy, or color change. Some of the physical properties of metals include high thermal and electrical conductivity, high luster, malleability, and ductility. Are your results in the same order? Different electron configurations, when combined with different ionization energies as required, produce ions of different charges. The reducing agent is bromine, and the oxidizing agent is manganese. Nonmetals will accept electrons to become negatively charged ions, called anions.
Place a piece of zinc metal in each row C well that contains solution. Solid metal was placed in a metal ion solution to determine if a reaction would occur. This was a key observation for calcium to be placed at the top of the activity series, because it was able to react with magnesium, zinc, iron, tin, and copper ions. The theory associated with this experiment is the atomic theory, more specifically electron configuration. Based on the number of reactions that occurred, aluminum would fall between magnesium and zinc on the activity series. Students also learn that the reactivity for the halogens is opposite that for the other families in the Periodic Table. Which of the metals reacted with the most solutions? Based on the observed reactivity in each case, students develop a separate activity series for the metals and the halogens.
Calcium should be the most reactive toward oxygen because it is the most reactive of the metals tested. Aluminum reacts with hydrochloric acid to produce AlCl 3 and hydrogen gas. The structure of the atom is responsible for the electron configuration. Some errors were human errors and were the result of lack of experience. However, while these properties do affect an elements place in the series, there are other factors that affect an elements activity An activity series of metals can predict whether a replacement displacement reaction will occur. This causes discrepancies between what should have happened in a given reaction and what was observed. The substance reduced is oxygen, and the substance oxidized is nitrogen.
