All of the following help control peroxide decomposition EXCEPT

  • A.raising the temperature as high as it will go
  • B.adding a silicate or organic stabiliser
  • C.sequestering iron and copper in the water
  • D.controlling the pH within a narrow working band

Answer: A

Correct answer: raising the temperature as high as it will go

Temperature accelerates decomposition rather than controlling it, so pushing it as high as possible spends the peroxide before it can do its work and damages the cellulose. The three genuine controls are a stabiliser to moderate the rate, sequestrants to remove the catalytic metal ions, and pH held within its working band.
