Varistors are often used to protect circuits against excessive transient voltage s by incorporating them into the circuit in such a way that, when triggered, they will shunt the current created by the high voltage away from the sensitive components.|

I was also surprise at how subtle Pb and Zinc and Pb in Iron could be, I feel that this lab was beneficial in honing our observational skills as some of the reactions where harder to see at first, such as Zinc in Magnesium. I also thought that the pipet was hard to get the accurate amount of drops out Also the time could play a role, if you recorded your observation at different points of the reduction series you might get different answers.
Based on your observations make an activity series of the metals used.
List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember, sodium and copper are metals, too.
Iron, Zinc, Lead, Magnesium B. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction.
Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate. Where does nickel fit into your activity series? Suppose you inserted a piece of an unknown metal into a solution of zinc II nitrate and observed no reaction.
Then if you inserted the unknown piece of the metal into the solution of iron III chloride a deposit formed on the bottom of the well in the well plate.
Where does the unknown metal fit into your activity series? The unknown metal would fit in between Zinc and Lead.
The element that is oxidized and the element that is reduced: Iron Fe was oxidized and the Ni was reduced. The oxidizing agent and the reducing agent Iron was the reducing agent and the Ni was the oxidizing agent.Effects of Oxidation in Everyday Life To understand the effects of oxidation state and its effect on everyday life we need to understand oxidation and more so the related reaction reduction as well.
The reduction and oxidation reaction or redox reaction is a chemical reaction during which the oxidation state of two or more of the reactants change.
Zinc Nitrate + Lead As zinc is more reactive, it replaces lead in the salt Oxidation-reduction reactions, redox reactions, are an important part of this experiment. In an oxidation reaction, a product will gain oxygen ions and will loose electrons.
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two atoms or compounds. The substance that loses the electrons is said to be oxidized, while the substance that gains the electrons is said to be reduced.
Oxidation-Reduction Reaction Of Magnesium Essay Sample. For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. The overall chemical reaction throughout the experiment will be balanced with the two oxidation-reduction reactions.
Within the household chlorine bleaches, sodium hypochlorite (NaOCl) and calcium hypochlorite Ca(ClO)2 are the oxidizing agents. Chemistry (12th Edition) answers to Chapter 20 - Oxidation-Reduction Reactions - 20 Assessment - Page 84 including work step by step written by community members like you.
