问题 等物质的量浓度的下列溶液中,C(NH4+)最大的是( )。
选项 A.NH4HS04 B.NH4HC03 C.NH4C1 D.NH4N03
答案 A
解析 {图}越大。HS04-电离出来的H+会抑制铵根离子水解,NH4HC03中HC03-会促进铵根离子水解,NH4C1和NH4N03溶液中的Cl-和N03-对铵根离子水解不产生影响。故NH4HS04。溶液中铵根离子浓度最大。故本题选A。

相关内容:浓度,溶液,A.NH4HS04,B.NH4HC03,C.NH4C1,D.NH4N03

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
