Calculating Avogadro’s Number Using ElectrochemistryBackgroundAs discussed in lecture, electrochemistry allows stoichiometric calculations to be relatedto current and time, if a chemical equation that relates electrons to reactants and products isknown. Recall that electrolysis involves using an electrical current to decompose a compoundinto simpler substances. This particular experiment will involve the electrolysis of a sulfuric acidsolution to generate hydrogen gas. By measuring the amount of hydrogen produced by thecurrent and length of time of the electrolysis, it is possible to calculate a value for the Faradayconstant and thus also Avogadro’s number. The amount of hydrogen is determined by utilizingthe ideal gas law (PV = nRT) to determine the number of moles of hydrogen produced in theelectrolysis.The amount of charge that has passed through the solution is measured in coulombs(C). It is calculated by measuring the current (in amperes, A) that has passed through thesolution…
