Representation of galvanic cell in general

• Anode|electrolyte of anode (conc)|| cathode|electrolyte of cathode(conc)

• Anode |electrolyte of anode(conc)||electrolyte of cathode(conc)|cathode

• Cathode |electrolyte of anode (conc)||anode|electrolyte of cathode (conc)

Representation of galvanic cell should at

Standard hydrogen electrode represented by

For SHE

potential , concentration of the solution and pressure always be

• Unity

• Zero

• Half

They are two types of reaction are possible in SHE depends on _________ we take

• Electrolyte

• Metal

• Potential

SHE act as both ____________ and ____________

In first case positive standard electrode potential is obtained due to copper is more stable than hydrogen , so Cu2+ ion get

• Oxidised

• Dissolved

• Reduced

The ____________ is inert electrode used in SHE
