Rate constants have been obtained from the rates of disappearance of the muonium precession signal in aqueous solutions of KMnOa,NaNOa, NaOH, NaCI, HCl, HC104, maleic acid and ethanol. They disqrce with the results of urtier, indirect determinations. Comparison with the rate constants for hydrogen a
