A novel route to pH oscillators
A novel route to pH oscillators
The formaldehyde–sulfite reaction is an acid to alkali clock reaction in batch, which displays complex behaviour in a flow reactor. Current published mechanisms do not account for the behaviour in an open system. In this Letter, we construct a minimal model based on this system and demonstrate that a base-catalysed rate-determining step coupled with an appropriate OH− consuming reaction can result in bistability and oscillations. The model may provide a method for the design of organic-based pH oscillators.

Abstract
The formaldehyde–sulfite reaction is an acid to alkali clock reaction in batch, which displays complex behaviour in a flow reactor. Current published mechanisms do not account for the behaviour in an open system. In this Letter, we construct a minimal model based on this system and demonstrate that a base-catalysed rate-determining step coupled with an appropriate OH− consuming reaction can result in bistability and oscillations. The model may provide a method for the design of organic-based pH oscillators.
