Edexcel IAL Chemistry A2 16.3 standard electrode conditions
Check every condition before calculating: gas pressure, 1 mol dm-3 ion concentrations and dilution from mixed salts all affect whether a half-cell is standard.
How this is tested
- Select 100 kPa hydrogen pressure and 1 mol dm-3 ion conditions for standard cells.
- Calculate solution concentrations or masses needed to prepare a standard half-cell.
