用铂电极电解浓硫酸可得到过二硫酸,但是过二硫酸会腐蚀铂吗?如果能腐蚀铂的话,常温情况下,腐蚀速度如何?很慢吗?

如果能腐蚀铂的话,常温情况下,在常温下,浓度为1 mol/L的过二硫酸对铂电极的腐蚀速率约为0.67mg/(cm²·h)。![](https://s.bdstatic.com/common/openjs/emoticon/img/face_246.png)

相关拓展:过二硫酸对铂电极的腐蚀机理是通过氧化还原反应造成的。过二硫酸在一定条件下可以发生氧化还原反应,其中SO4²⁻离子会被还原为SO₂或者S,该过程会产生硫酸和硫酸酸化物。在此过程中,铂电极会充当电子传递媒介,参与氧化还原反应,因此铂电极会被腐蚀。这个过程是缓慢进行的,在实际应用中,铂电极的腐蚀情况可以忽略不计哦![](https://s.bdstatic.com/common/openjs/emoticon/img/face_246.png)

哦哦,知道了。
如果用铱铂电极或铱钌电极的话,能不能胜过铂这个情况。
可以
