  1. 是非题: 1、导电能力强的电解质 溶液一定是强电解质溶液 2、强电解质溶液的导电 性一定比弱电解质溶液 的导电性强

  2. 1、10ml 0.1mol/L的HCl 和CH3COOH哪种溶液中 的[H+]大? 2、[H+]相同的HCl和 CH3COOH,哪种溶液的物 质的量浓度大?

  3. 例1: 1L 0.1mol/L的醋 酸溶液,含有H+1.32× 10-3mol求氢氟酸的电 离度?

  4. 例2: H+浓度为1×10-3 mol/L的氰氢酸,已知 电离度为0.01%,则HCN 的物质的量浓度是多 少?

  5. 练习: 某温度下某一元弱酸溶 液里分子和溶液中电离 出来的离子物质的量之 比为9:2,则一元弱酸在 该温度的电离度是多少?

  6. CH3COOH CH3COO-+H+
