## Effect of Varying Concentrations of Hydrogen Peroxide and Potassium Iodate on the Rate of the Briggs-Rauscher Oscillating Reaction

Chemistry

The purpose of this investigation is to determine the effects of varying initial reactant concentrations on the overall rate of the reaction. This is then used to calculate the overall

## Complexometric Determination of Nickel using EDTA

Chemistry, Analytical Chemistry

EDTA, or ethylenediaminetetraacetic acid is able to form stable complexes with nickel ions due to its hexadentate structure with a one-to-one ratio:  EDTA^{4-}_{(aq)} + Ni^{2+}_{(aq)} \rightarrow [EDTA
