Which two metals combined together give the higher voltage when reacting with acid :: GCSE Chemistry Coursework Investigation

Which cardinal alloys combined together give the higher(prenominal) voltage when defending with cuttingIntroductionIn this investigation we give find aside which two metals combinedtogether give the higher voltage when fight downing with stifling. The metalsused lead be Aluminium Zinc Iron Tin Lead nickel note CopperTo make a prediction on what metals will be the ones that give thehighest voltage when combined together you need to find out if theposition in which the metals argon at in the reactivity serial publication wouldmake a difference, and if it does, how? You also need to find out howthe metals react with acids.We know that the higher the metal is in the reactivity series, thestronger it will react with an acid.TheoryBatteries maintain chemicals inside to store energy. When two differentmetals that be connected by a wire are placed into an acid, a potentiality difference (voltage) is produced. This occurs because themetals react with the acid forming Hydrogen ac id, a metal saltsolution and an electric charge. The charge flows from the nearlyreactive metal to the least reactive metal.EquipmentThe equipment used will be Acids Metals Wires Voltmeters Beakers Measuring cylinders forbear watches SandpaperMethodCollect all the equipment and place it as it is shown on the diagramabove. Choose around 10 partner offs of metals and place one pair in thebeaker, and connect them both with a wire. Put them in for a fewseconds, and voltage will be produced when the two metals react withthe acid forming hydrogen, a metal salt solution and an electriccharge. This charge will flow from the least reactive metal to themost reactive metal. euphony the voltage with the voltmeter and writeit down. Do this for every pair of metal you have chosen, and thenfind out which ones are the most reactive and which ones are theleast.PredictionI predict that the highest metal in the reactivity series and thelowest metal in the reactivity series from the metals we are employwill produce the highest voltage. I think this because voltage is alsocalled potential difference, so this shows that there is more powerwhen the difference between the metals is larger. This kernel that thevoltage in the metal which is lower in the reactivity series must havea higher voltage to the metal that is most reactive to make myprediction correct. I think that the highest the difference = thehigher the voltage.I also predict that changing the acid will switch the ending result. Ithink that the stronger the acid, the higher the voltage.
