第10题
第11题
11. 探究分子运动的创新实验装置如图所示,实验时旋开玻璃旋塞,观察酚酞试纸的颜色变化。下列说法错误的是 (　　)


解析　溶液pOH越大，溶液中氢氧根离子浓度越小，FeO的物质的量分数越小，H3FeO的物质的量分数越大，由图可知，曲线Ⅰ代表FeO的变化、曲线Ⅱ代表HFeO的变化、曲线Ⅲ代表H2FeO4的变化、曲线Ⅳ代表H3FeO的变化，①、②均不正确；FeO＋H2O??HFeO＋OH－的平衡常数K1＝，当c(FeO)＝c(HFeO)时，K1＝c平(OH－)，由图可知a点c(FeO)＝c(HFeO)，pOH＝1.6，则K1＝10－1.6mol·L－1，同理可知HFeO＋H2O??H2FeO4＋OH－的平衡常数K2＝10－3.2mol·L－1，H2FeO4＋H2O??H3FeO＋OH－的平衡常数K3＝10－7.3mol·L－1，FeO＋3H2O??H3FeO＋3OH－的平衡常数K＝＝××＝K1×K2×K3＝10－12.1mol3·L－3，③正确；b点溶液中c(HFeO)＝c(H2FeO4)，溶液中存在电荷守恒关系：c(Na＋)＋c(H＋)＋c(H3FeO)＝c(OH－)＋2c(FeO)＋c(HFeO)＋2c(SO)，溶液中c(SO)≠c(HFeO)，则b点溶液中c(Na＋)＋c(H＋)＋c(H3FeO)≠c(OH－)＋2c(FeO)＋3c(HFeO)，④错误。
