the factors affecting the rate of a chemical reaction 1. Aim of investigation To investigate the major factors that affect the rate of corrosion. 2. Motivation (explain why you have chosen to investigate this particular topic) I have chosen to examine this experiment as it applies to our daily lives. Rusting of metal occurs every day whether it’s the nails on our deck or that rusting bicycle in our garage. Considering that rust is such a worldwide problem‚ I wanted to conduct my own explanation

Barnuevo CHEM 17.1 13L Group 1 February 7‚ 2014 February 19‚ 2014 Exercise 12 SOME INVESTIGATIONS ON THE CORROSION OF IRON I. Introduction Metals undergo natural destruction that allows a spontaneous deteriorating reaction where they return to their original state from where they are obtained upon contact with the surrounding‚ particularly when reacted to oxygen. Such phenomenon is known as corrosion (Zumdahl‚ 1998). This leads the surface of the materials to rust in due time. Usually‚ this kind of process

Many metallic substances such as steels‚ cars and ships become subjects to corrosion all the time. Corrosion is a process that happens over a period of time when

Section Assignment 3.4 Part F – The Reaction of Iron Nails with a Copper Solution Introduction: The experiment in this activity involves the reaction between a copper (II) chloride solution with iron nails and the mole ratios involved in the reaction. Measurements are taken to determine the moles of each reactant involved in the reaction and thus the number of atoms or molecules involved. Apparatus and Materials: Refer to the reaction of iron nails with a copper solution assignment in Module

The purpose of this lab was to find out the reaction of iron nails and CuSO4‚ copper sulfate solution. Before starting the experiment‚ there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges‚ +2 and +3. As the liquid evaporated‚ the weight changed because the liquid added to the nail’s weight. In a real world situation‚ scientists can use ratios to determine how much of a substance that

kettles‚ fridges and many more things. These are the most basic uses of metals‚ but the need for metals also enters a chemical level‚ they are massively important in chemistry. The aim of this report is to determine what the best prevention method of corrosion will be in the ships in two different conditions; cold‚ deep water and warm‚ shallow water. It will also analyse these prevention costs and justify which prevention method would be the best (environmentally and financially) or if it is simply better

Introduction Corrosion is defined as the degradation of materials by chemical interaction with their
Premium Corrosion
Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Both the type of metal and the environmental conditions‚ particularly what gases that are in contact with the metal‚ determine the form and rate of deterioration. The most common example of corrosion is‚ of course‚ rust. The reddish-brown compound referred to as rust is actually iron oxide (Fe2O3)‚ a result of reactions between oxygen and iron. But the oxidization of iron is
Premium Corrosion
Corrosion Let metal sit surrounded by oxygen for a while and the metal will corrode. Corrosion is the chemical reaction that takes place when a metal is in contact with oxygen. The metal reacts with the oxygen to form a compound called an oxide on the surface of the metal. The metal becomes tarnished and loses its shine. Metals high in the reactivity series (an observable series of metals‚ in order of reactivity from highest to lowest) corrode more quickly than less reactive metals
