Potential difference

Year 12

The more electronegative the atom is, the more_____ the oxidation number is Negative
Which are the three most electronegative elements? 1. Fluorine 2. Oxygen 3. Chlorine
What are metal displacement reactions? Reactions between a metal and a solution containing the ions of a different metal.
What are displacement reactions also known as? oxidation/reduction reactions, redox reactions
What happens in a metal displacement reaction? Metal converts the ion of another metal to the neautral atom, hence producing another solid.
What is the electromotive force? What is it measured in? EMF, Potential difference across electrodes, measured in volts.
Standard electrode potentials are measured relitively to the standard_______ electrode Hydrogen
What voltage is the standard hydrogen electrode set at? 0.0V
Measurements in relation the the hydrogen electrode are done at which concentration, pressure and temperature? Concentration: 1.00molL-1 (H+ ion) Pressure: 100 KPa (H2 gas) Temperature: 25C
Consider a galvanic cell that produces the overall reaction Zn(s) + Cu2+ (aq) ---> Zn2+(aq) + Cu(s) Find out the total E +1.1V
Draw the Zn(s)+Cu2+(aq) ---> Zn2+(aq) + Cu(s) vertical lines for the potetial E Zn(s)|Zn2+(aq)||Cu(aq)|Cu(s)
Describe what happens when copper metal is placed in a solution of Ag ions - Copper oxidises - Ag reduces and gains an electron, forming ag metalic
