1.选择题(共8题)

1.下列说法错误的是(   )

①NaHCO3溶液加水稀释,c(Na+)/c(HCO3)的比值保持增大

②浓度均为0.1mol•L﹣1的Na2CO3、NaHCO3混合溶液:2c(Na+)=3[c(CO32)+c(HCO3)]

③在0.1mol•L﹣1氨水中滴加0.1mol•L﹣1盐酸,恰好完全反应时溶液的pH=a,则由水电离产生的c(OH)=10﹣amol•L﹣﹣1

④向0.1mol/LNa2SO3溶液中加入少量NaOH固体,c(Na+)、c(SO32)均增大

⑤浓度相等的①NH4HSO4溶液、②NH4HCO3溶液、③NH4Cl溶液中的c(NH4+):①>②>③

⑥NaHSO3溶液显酸性,c(Na+)>c(HSO3)>c(H+)>c(OH)>c(SO32

⑦常温下,CH3COONa和CH3COOH混合溶液[pH=7,c(Na+)=0.1mol•L﹣1]:c(Na+)=c(CH3COO)>c(CH3COOH)>c(H+)=c(OH

⑧pH=3.6的0.1mol/L HX与0.1mol/L NaX的混合溶液中,c(H+)﹣c(OH)=c(X)﹣c(HX)

2.下列溶液中粒子的物质的量浓度关系正确的是(   )
3.下列溶液中粒子的物质的量浓度关系正确的是(   )

6.向amol/L的氨水中加入等体积b mol•L﹣1的盐酸,下列关系错误的是(   )
7.以下指定溶液中有关离子的物质的量浓度关系正确的是(   )
8.向10mL 0.1mol•L﹣1NH4Al(SO42溶液中,滴加等浓度Ba(OH)2溶液x mL,下列叙述正确的是(   )
