I'm trying to clean pencil marks off of my aluminum sidingI'm used alcohol but it is not all coming off.
First, you must understand what a redox reaction is; it is a reaction in which the elements change chargeFor H3O+-H2O, hydrogen and oxygen to do not change charge since on both sides of the reaction hydrogen has a 1+ charge and oxygen has a 2- chargeSo H30+ is not reduced or oxidizedMnO2 is an oxidizing agent because the charge on the Mn changes from 4+ to 2+An oxidizing agent is the component that has it's charge reducedCl- is a reducing agent because the charge on Cl goes from 1- to 0A reducing agent is the component that loses electrons, or gets a greater charge.
OILRIGOxidation Is LossReductions Is GainSo Aluminium has gained electrons so it has been reduced, so Aluminium is the oxidising agentIt ha caused something to lose it's electrons so Al has been reducedHydrogen has been oxidised so hydrogen is the reducing agent.
Use a white (or that natural rubber band-colored kind) eraserA pink one will leave pink marks.
