Interaction of noise with nonlinear chemical dynamics is studied experimentally. In particular, noise invoked resonance phenomena are investigated. The existence of the standard Coherence Resonance (CR) and Periodic Stochastic Resonance (PSR) effects, manifested by signature unimodal curves, are verified in experiments. Moreover, the possibility of the coexistence of CR and PSR is entertained. This coexistence is subsequently confirmed by the bimodal shape of the generated resonance curve.
