実験手順

A 2 liter flask was charged with an aqueous solution of barium dithionate (all of the solution from 1b) and an equimolar amount of solid CuSO4 (a very concentrated aqueous solution can be used, addition with vigorous stirring). Vigorous stirring was maintained for about 3 hours following which time the white suspension of BaSO4 was filtered. The resulting deep blue solution of copper dithionate was evaporated in-vacuo to yield solid copper dithionate as a blue crystalline material (approximately 55% yield based on MnO2 with less than 0.8% sulfate impurity by IC analysis).
