1、导电能力强的电解质 溶液一定是强电解质溶液

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. 1、 10 ml 0.1mol/L 的 HCl 和 CH 3 COOH 哪种溶液中 的［ H + ］ 大？. 2、 ［ H + ］ 相同的 HCl 和 CH 3 COOH， 哪种溶液的物 质的量浓度大？. 例1： 1 L 0.1mol/L 的醋 酸溶液,含有 H + 1.32× 10 -3 mol 求氢氟酸的电 离度？. 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

  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+
