Reaction of Metals with Water 1. When a displacement reaction occurs, heat energy is given out which means that the reaction is exothermic. Write appropriate half-equations to illustrate this concept. In theory, when a more reactive metal takes part Activity series essay a displacement reaction, the reaction is more vigorous and exothermic.
Use the reaction of zinc with hydrochloric acid to illustrate this. Moreover, it will be the hottest when the reaction between magnesium and copper sulphate takes place. Calcium is a very reactive metal with water and therefore reacting with acid may be too dangerous.
Reaction of Metals with Acids 1. The chemical equations for the reactions that will take place are as follows: If bubbles of gas are produced, test the gas with a lighted splint.
Clean each piece of metal with emery paper sand paper until it is shiny. This happens because the compound on the reactants side is quite unstable and thus breaks up easily and so much energy is not used up.
The rise in temperature for each of the metal powders to be used is shown after a period of 2 minutes for each reaction. If a reaction is not visible, heat the water until it boils. Write a balanced chemical equation for the reaction of calcium with water.
Pour 5 Ml of hydrochloric acid into each of the eight test tubes. Press enter to begin your search Reactivity of Metals: Acids corrode some metals, while other metals are resistant to corrosion.
Carefully slide into each test-tube a piece of each polished metal. For example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second.
Simultaneously observe the reaction of each metal in the test-tubes and record all observations. To investigate and see the reaction of four metals- magnesium, zinc, aluminium and iron with copper sulphate to find out which one is the most reactive and which one the least reactive.
Therefore in this reaction, a more reactive metal will displace the metal ion in the compound and thus it will be separated. Iron oxide flakes off, exposing the underlying layer of iron to attack by the environment. However, the general products of corrosion in acids are salt and Hydrogen gas is evolved.
Need essay sample on Reactivity of Metals: If apparent changes are not visible, allow the metal to be left on a gauze mat until it cools and examine again.
Hold each metal under a Bunsen flame and wait until the metal becomes very hot or melts. The rise in temperature will become lesser in the order of reactivity and therefore the reaction between rion and copper sulphate will be the least reactive and will take the longest time for the reaction to complete.
Aluminium oxide is a thin, invisible film on the surface of the metal that prevents it from reacting with the environment.
Make sure to wear eye protection and skin protection in order to prevent harm or contact with the Hydrochloric Acid.
Moreover we also see that the reaction with magnesium took the shortest time to complete. Drop a piece of each metal into a test-tube containing about 5 Ml cold distilled water.
What were your criteria to establish the above activity series of metals? Mg, Al, Zn and Fe. This reaction is carried out using the metal powder given and a weak compound such as copper sulphate in which the metal ion is lower than the metal powder in the reactivity series.
They have to take part in a reaction with copper sulfate which is an aqueous solution and its metal ion is copper.
When an unstable compound is broken, not much energy is used up and thus it is expected that all four reactions will be exothermic. The prevention of oxide formation is an expensive battle.In introductory chemistry, the reactivity series or activity series is an empirical series of metals, in order of "reactivity" from highest to lowest.
It is used to summarize information about the reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores. Essay Writing Worksheets and Printables.

Students read about Yousafzai's life, then answer a series of thoughtful questions about both education and the issues. Essay about Activity Series ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to. Traditional Structure Activity.
An essay is based on a series of ideas and assertions in the thesis and topic sentences (which are like mini thesis sentences). Free Essay: Commentary On A Police Series Episode The commentary I am going to write about is on a police series called the Bill.
The Bill first started in. For example my hypothesis in a reaction of Mg and Pb is that; Mg being a more reactive metal in the reactivity series will displace Pb, a least reactive metal in the series. We will write a custom essay sample on Reactivity series for common metals experiment specifically for you.Download
