Question 1

how do you draw a standard hydrogen half cell?

Answer 1

• platinum electrode
• beaker of H+(aq) solution (1moldm-³)
• gas syringe and delivery tube providing solution with H2

Question 2

standard conditions for half cells

Answer 2

• 1moldm-³
• 1 atm
• 298K

Question 3

standard electrode potential

Answer 3

the e.m.f of a half cell compared with a standard hydrogen half cell measured at 298K with solution concentrations of 1moldm-³ and a gas pressure of 1atm
