Daniell cell - a chemical cell in which electrons flow from the zinc strip to the copper container in the external circuit

Electrochemical series - the order of the different tendencies of metals to form ions

Half-cell - the oxidation or reduction half of a chemical cell

Ionic half-equation - the oxidation half or the reduction half of an oxidation-reduction reaction

Metal couple - the two metals which undergo redox reactions in a chemical cell

Porous pot - acts as a porous barrier allows ions to pass through but prevents the solutions from mixing

Salt bridge - a piece of filter paper soaked with an ionic salt solution; used to connect the two half-cells of a chemical cell
