Sulfur dioxide turns aqueous acidified potassium manganate (IIV) from purple to colorless. a piece of filter paper soaked in aqueous acidified pottasium manganate(IIV) is glued to the top of the gas jar of air. the glass plate is removed. at first, the filter paper remains purple. After a short time, the filter paper turns colorless. explain the results in terms of the kinetic particle theory.
