(a) 0.13 M KNO2
_______
(b) 0.43 M NaOCl
_______
(c) 0.36 M NH4ClO4
_______
Calculate the pH of each of the following solutions.(a) 0.13 M KNO2_______(b) 0.43 M NaOCl_______(c) 0.36 M NH4ClO4_______
查,NO2-,OCl-,NH4+的解离常数,计算.如果查不到,可以查相应酸的Ka或碱的Kb值,用水的离子积去除以Ka或Kb即得.
由NO2-+H2O=OH-+HNO2,
忽略水的电离
[OH]^2/[NO2-]=K
NO2-=0.13
求[OH-],求【H】.
注意有时不能忽略水的解离,不能简化计算.详见分析化学相关资料.
你是要算pH的啊!
因为太多了!具体请您参看《分析化学》 (第五版) 上册 武汉大学 主编 的第119页到第127页!
看了你就明白怎么算了!
嗯。。很好很强大。。。你这问题悬赏0分还这么有难度,估计没几个人乐意给你答案,自己慢慢找吧。。。
