Worked Example: Calculating Quantity of Charge (iii) electrolysis of aqueous solutions to extract an element:Įxample from industry: electrowinning of copper (ii) electrolysis of molten salts to extract a metalĮxample from industry: extraction of aluminium from bauxiteĮxample from industry: extraction of sodium from molten soduim chloride This equation can be used to determine the quantity of charge, electric current, or length of time required to run an electrolysis experiment such as:Įxample from industry: electrorefining of copper.This equation can be rearranged to calculate the time taken given the quantity of charge (electricity) and the electric current:.This equation can be rearranged to calculate the electric current given quantity of charge (electricity) and time:.Q = quantity of charge (electricity) in coulombs (C)
The quantity of charge (or electricity) contained in a current running for a specified time can be calculated:.The amount of charge is given the symbol Q and is measured in units of coulombs (C). The amount of charge passing a point in an electric circuit depends on the electric current and the time the current is allowed to flow for.This flow of electrons is called an electric current.Ĭurrent is given the symbol I and is measured in units of amperes (amps, A). A galvanic cell (voltaic cell) produces a flow of electrons.You need to become an AUS-e-TUTE Member!
