Gold‐nanoparticle‐modified electrodes find wide and diverse applications in the area of electrochemistry. We demonstrate for the first time that gold‐nanoparticle‐modified electrodes can provide mechanistic information and we exemplify this with the electrochemical deposition of arsenic(III). Our approach of using nanoparticle ensembles is a facile and economical methodology that provides an alternative to using expensive gold single‐crystal electrodes that require careful surface preparation before each measurement.
