Place a small piece of each of the … Reactions of metals and acid. Metals low in activity series are very: EASY. Reactivity of metals Aim: To compare the reactivity of various metals by observing their reaction with hydrochloric acid Hypothesis: Variables: dependent/ independent Materials: * 2 M hydrochloric acid * Detergent * Test tubes and test tube rack * 0.5cm pieces of magnesium, aluminum, iron, zinc and copper * Steel wool * Ruler * Timer * Bench Mat Investigate the reactivity of metals. Lab Session 6, Experiment 5: Hydrogen and the Activity Series of Metals An activity series is a listing of chemical species in order of increasing (or decreasing) reactivity. This practical is part of our Classic chemistry experiments collection. Reactions between Dilute Hydrochloric and Sulfuric Acid with Metals: Acids react with most metals and, when they do, a salt and hydrogen gas is produced: Metal + Hydrochloric Acid → Metal Chloride + Hydrogen. He holds an Honours in Accountancy degree from the University of Zimbabwe. He is passionate about technology and its practical application in today's world. It’s not just the arts that are creative, chemistry is too. Challenge your 14–16 students with this chemistry-themed quiz. Hydrogen burns rapidly with a pop sound. Hydrochloric acid makes a CHLORIDE Sulphuric acid makes a SULPHATE Nitric acid makes a NITRATE 4 Complete the following word equations for the reactions between the four metals and hydrochloric acid: To compare the reactivity of various metals by observing their reaction with hydrochloric acid. To prepare dilute hydrochloric acid solution, slowly and carefully add approximately 100 ml concentrated hydrochloric acid (33% or 11 M) to 900 ml of cold tap water. About 3 mm long in each test tube, Note the evolution of hydrogen bubbles and compare the different rates at which the bubbles are formed, Make a table of results noting whether the evolution of hydrogen bubbles was rapid, slow, very slow or none apparent, The most reactive metals like magnesium and zinc reacted much more quickly with dilute acid. Aim: To compare the reactivity of metals in oxygen, water and a diluted acid, and rate the metals from most reactive to least reactive. Physical properties of metals METALS Solid state at room temp Shiny appearance High density Good heat conductors Good conductors of electricity High Melting and Boiling point Ductile and malleable Strong and tough Except Mercury (Liquid) Due to strong forces (metallic) except Mercury and alkali metals … We also examine what it is that determines the reactivity of the metal. Therefore, the reactivity series of metals can be used to predict the reactions between metals and water. Arrangement of Metals in Reactivity Series . 2. C1.1.12 describe tests to identify oxygen, hydrogen and carbon dioxide, Unit 1: THE LANGUAGE OF CHEMISTRY, STRUCTURE OF MATTER AND SIMPLE REACTIONS, (h) trend in general reactivity of Group 1 and Group 2 metals, Unit AS 2: Further Physical and inorganic Chemistry and an Introdution to Organic Chemistry, 2.11 Group II elements and their compounds. Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. If anything goes wrong, chat with us using the chat feature at the bottom right of this screen. Metals (be sure you can locate them on the periodic table) tend to react by losing one or more electrons (per atom). Classification of the first twenty elements in the periodic table on the basis of the number of outer electrons. This video shows how HCL reacts with the metals Aluminum, Zinc, Copper, Vanadium, Cadmium and a few others. We can put metals in order of their reactivity by investigating how well they react with water or hydrochloric acid. Method. Aim: To examine the reactivity of metals with dilute hydrochloric acid. When a gas is formed in a reaction, it releases bubbles. Experiment: The reaction of metals with dilute Hydrochloric acid, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Quick NetOne, Telecel, Africom, And Econet Airtime Recharge, on Experiment: The reaction of metals with dilute Hydrochloric acid, O Level Computer Science: Software: Operating Systems: Personal Computers, O Level Computer Science: Software: Operating System, O Level Computer Science: Hardware: Point Of Sale Terminal, O Level Computer Science: Hardware: Automated Teller Machine, O Level Computer Science: Hardware and Software: Introduction, Place about 5cm depth of the acid in each of the five test tubes, Place a small piece of each of the three metals above. The reactivity series of metals, which lists metals from most reactive to least reactive, can be used to predict which metals will react with acids. The surface of the magnesium was cleaned with a piece of sandpaper 2. Investigate reactions between acids and bases; use indicators and the pH scale. To access more topics go to the Combined Science Notes page. Reactivity Series Experiment Pre-Lab Answers: 1. Define the reactivity series of metals. In this activity we use a set of controlled experiments with hydrochloric acid to place some common metals in a reactivity series. If the metal reacted with citric acid then a metal citrate was made.
