•Air nanobubbles were formed after depressurisation of saturated air in reagentized solutions.•Zeta potential values displayed sigmoidal pH behaviour between pH 2 (+26mV) and 8.5 (−28mV).•The nanobubbles had an isoelectric point at pH 4.5.•The size of the nanobubbles depended on zeta potentials, big...
