Reactivity Series of Metals

Extracts from this document...

Introduction

Reactivity Series of Metals When elements are placed in order of their chemical reactivity the sequence is known as an activity series. It is normally used only for metals, together with the non-metals carbon and hydrogen. The list is arrived at by comparing the reactions of these metals with oxygen, with water, and with dilute acid. The activity series is in fact a list of metals in order of the ease with which they form ions. The activity series is more commonly known as the reactivity series. The list of elements in order of their ability to lose electron (i.e. in order of their standard electrode potentials) is sometimes called the electrochemical series (E.C.S.). It is virtually the same as the reactivity series except it can be extended to include many other substances rather than just the metals, carbon and hydrogen. The hydrogen electrode is just one example of the way non-metals that are neither solids nor conductors can be included in the E.C.S. Calcium is included in the reactivity series but not in the E.C.S. This is because the electrode potential of calcium is not quite as expected from its chemical reactivity. ...read more.

Attacked by dilute acids. (Al is only attacked by dilute HCl). In practice the first 4 are too reactive to risk safely. Mg + 2HCl MgCl2 + H2 Mg + H2SO4 MgSO4 + H2 Pb H Cu Hg Forms oxide when heated in air. 2Cu + O2 2CuO Do not decompose in water or steam at red heat. Attacked by oxidizing acids e.g. Nitric Acid Ag Au Pt Unaffected by Oxygen. Unaffected by acid. This table which concerns the reactions of the elements with oxygen, water and dilute acids has placed the elements in order of decreasing reactivity as the table is descended. The order in which the elements are arranged with aspect to their relative reactivity is known as the reactivity series. It is a useful list to know and can be remember by the following mnemonic (learning aid).

Conclusion

Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Hydrogen Copper Mercury Silver Gold Platinum Extraction of Metals Metals low in the reactivity series, such as silver and gold, may be found free in nature (native state) but most metals occur as compounds in the form of metal ore. There are two main methods for extracting metals from their purified and concentrated ores: a) Reduction of the metal oxide by carbon (coke) b) Electrolysis of the molten chloride or oxide The oxides and sulphates of some metals near the bottom of the reactivity series are so unstable that they can be decomposed by the action of heat alone. The table below shows how the method of extraction is related to the position of the metal in the reactivity series. The higher the metal in the reactivity series the more severe or drastic the method of extraction needs to be.

    and are held together by delocalised electrons. Metals can be visualized more or less like billiard balls arranged in order, which is why they can move across each other and that is why the metal can deform. Carbon is important in the extraction of iron.

  2. The aim of this experiment is to determine the order of the reactivity series ...

    The metal gives off bubbles, which we already know are hydrogen. Hydrogen and metals below this don not react with acid. Therefore gold won't react with acid because it is below hydrogen in the reactivity series, and therefore can't displace hydrogen.

  1. Thermal Decomposition Of Metal Carbonates

    The less reactive metals such as Aluminium and Zinc can be placed in dilute acid to see how they react because they don't react in a dangerous way. The metal upon being placed in the acid does not explode or burn.

    The most reactive is the metal, which displaces the most of the solutions. The experiment confirms that magnesium is more reactive than the other metals. Magnesium reacts and forms its ions whilst other metals are displaced from the solution. The reactants also give out heat when reacting with the acid this is called an exothermic reaction.

    It is also resistant to corrosion and can be easily bent into any shape. Aluminium is a good conductor of heat and electricity. It can be polished to achieve a highly reflective surface. Aluminuim can be used for making aircraft, lightweight vehicles, and ladders because it has a low density and it is strong.

  2. Thermal Decomposition of Metal carbonates

    This type of reaction is called a displacement reaction. The metal takes the place of the hydrogen in the acid, which means that hydrogen is given off. It is too dangerous to do this reaction with Potassium, sodium and calcium, because these metals violently explode when they are placed in dilute acid.

    Most metals are extracted using reduction reactions usually of metal oxides. This reduction of the metal compound is usually done in one of three main ways: * by heating with carbon (in the form of coke) * by heating with a more reactive metal (active metal)
