Title: half reaction method Post by: Nathan on October 06, 2009, 05:58:12 AM Pb+PbO2+H2SO4---> PbSO4 balance this with half reaction method
Title: Re: half reaction method Post by: kingchemist on October 06, 2009, 06:23:06 AM There are two reactions which fit the categories:
acid + metal ---> salt + hydrogen and acid + metal oxide ----> salt + water Pb + H2SO4 ----> PbSO4 + H2 PbO2 + H2SO4 ----> PbSO4 + H2O this cannot be balanced. I am also concerned with the chemicals involved in this reaction as PbSO4 is an insoluble salt and in the first reaction, some PbSO4 would be made as a coating and then the reaction would stop. The same would true with the second reaction. So effectively, there is virtually no reaction. |
