i2o5和氢氧化钾反应是3KOH加H3PO4等于K3PO4加3H2O。碘即是氧化剂也是还原剂。
I2+2KOH=KI+KIO+H2O 碘即是氧化剂也是还原剂。五氧化二磷与氢氧化钾的反应是3KOH+H3PO4=K3PO4+3H2O
氢氧化钾与磷反应：按照反应物的多少来判断，若磷酸多， H3PO4 + KOH = KH2PO4 + H2O H3PO4 + 2KOH = K2HPO4 +2 H2O 若碱多 H3PO4 + 3KOH = 3H2O + K3PO4 反应条件是热浓氢氧化钾
3=AgCl↓+HNO3 B.3KOH+H3PO4=K3PO4+3H2O C.CuO+H2=△Cu+H2O D.NH4Cl+NaOH=NaCl+NH3↑+H2O 相关知识点: 试题来源: 酸的通性pH值练习题 解析 答案:B。 中和反应是指酸和碱作用生成盐和水的反应,反应物是酸和碱; A、AgNO3不是碱,故A错误; B、氢氧化钾是碱,磷酸是酸,两者中和生成盐...
