The second order, homogeneous reaction between sodium thiosulphate and hydrogen peroxide was used to study the mixing in a 2.5‐liter, continuous flow stirred tank reactor and in a 50‐gallon pilot unit. The residence time distribution was measured with deionized water and pulse injection of a tracer. At low speeds the agitation was related to a “segregation” model. The region of “maximum mixedness” and the onset of “perfect mixing” were correlated with both horsepower input and recirculation rate within the reactor.
