，稀释KOH溶液
、等浓度的稀盐酸反响
：甲+乙→丙+丁，以下判断正确的选项是
、乙、丙、丁不可能含有同一种元素
、丁为水，那么该反响一定为复分解反响
、乙为化合物，那么该反响一定为复分解反响
(NO3)2,那么甲可能为单质、氧化物、碱或盐
甲、乙两种物质的溶解度曲线如图1所示。以下说法中正确的选项是
℃时，甲饱和溶液的溶质质量分数大于乙饱和溶液
B. t2℃时，甲、乙饱和溶液的溶质质量分数都为30%
C. t2℃时，甲、乙的饱和溶液分别降温至t1℃，甲溶液
饱和，乙溶液不饱和

of rural drinking water sources, protection of drinking water sources in rural areas by the end of the delimitation of the scope of protection, complete with warning signs, isolating network protection facilities
of rural drinking water sources, protection of drinking water sources in rural areas by the end of the delimitation of the scope of protection, complete with warning signs, isolating network protection facilities
D. t2℃时，质量相同的甲、乙饱和溶液分别升温至t3℃，
为达饱和状态，需参加甲的质量大于乙
