Abstract: Basic carbonate of Pr(Ⅳ) being dissolved in aqueous solution of acetic acid gives an yellow Pr(Ⅳ)-Ac- complex which shows a broad characteristic absorption band at 266nm.The ratio of Pr(Ⅳ): Ac- in complex as determined by equilibrium shifting method is 1:4.It is found that the reduction of Pr (Ⅳ)-Ac- complex in aqueous acetic acid solution is a pseudo first order reaction.
