Electrochemical Series The?E??values of a species indicate how?easily?they can get?oxidised?or?reduced In other words, they indicate the relative?reactivity?of elements, compounds and ions as?oxidi...
Calculating Standard Cell Potential Once the standard electrode potentials (E?) of the half-cells are determined, the?standard cell potential?(Ecell?) can be calculated by?subtracting?the?less?posi...
Calculations in Electrolysis Faraday’s constant?can be used to calculate: The?mass?of a substance?deposited?at an electrode The?volume?of gas?liberated?at an electrode Calculating the mass of a sub...
Measuring the Standard Electrode Potential There are three different types of half-cells that can be connected to a standard hydrogen electrode A metal / metal ion half-cell A non-metal / non-metal...
7月5日，IB成績下發，7月6日下午英國時間12:00起，IBDP考生可以開始上網查成績。與此同時，7月5日UCAS補錄開始開放，不過7月5日開始early clearing，適用于IB和AP應屆生，以及已獲得最終成績的往屆生。8月18日，...
Standard Electrode & Standard Cell Potentials Electrode potential The?electrode (reduction) potential?(E) is a value which shows how easily a substance is?reduced These are demonstrated using r...
Faraday's Law The?amount?of substance that is formed at an electrode during?electrolysis?is proportional to: The amount of?time?where a constant current to passes The?amount?of?electricity, in coul...
Products of Electrolysis Electrolysis?is the breaking down of a compound into its elements using an?electric current For example, the electrolysis of zinc chloride (ZnCl2) into its elements zinc an...
Feasibility & Temperature Changes The?feasibility?of a reaction can be affected by the?temperature The Gibbs equation will be used to explain what will affect the feasibility of a reaction for ...
The Gibbs Equation: Reaction Feasibility The Gibbs equation can be used to calculate whether a reaction is?feasible?or not ΔG??= ΔHreaction??- TΔSsystem? When ΔG??is?negative, the reaction is?feasi...
The Gibbs Equation Gibbs free energy The feasibility of a reaction does not only depend on the entropy change of the reaction, but can also be affected by the enthalpy change Therefore, using the e...
