问题 加盐酸后晶体溶解
选项 A.草酸钙晶体 B.碳酸钙晶体 C.淀粉粒 D.硅质块 E.糊粉粒
答案 A
解析 糊粉粒加稀碘液显暗黄棕色,遇米隆试液显砖红色。草酸钙晶体加盐酸后晶体溶解。硅质块加硫酸后晶体不溶解,加氢氟酸溶解。碳酸钙晶体加醋酸后晶体溶解,并产生气泡。

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). Please check the Redis logs for details about the RDB error.
