Effects of sulphate and perchlorate ions on an oscillatory reaction of the Belousov–Zhabotinskii type with oxalic acid
Abstract
The Belousov–Zhabotinskii reaction with oxalic acid in a closed, stirred batch reactor has been investigated in H2SO4–NaHSO4, H2SO4–SO2–4(cations Na+ or Mg2+) and H2SO4–MClO4(M+= Na+ or Li+) mixtures. While the addition of sulphate ions has little effect on the oscillating reaction, perchlorate ions can inhibit it or increase the number of oscillations.
