But without deeper (2)_____ one knows from daily life that one exists for other people—first of all for those upon whose smiles and well-being our own happiness is wholly (3)_____, and then for the many unknown (4)_____ us, (5)_____ destinies we are bound by the ties of sympathy. A hundred times every day I remind myself (6)_____ my inner and outer life (7)_____ the labors of other men, living and dead, and that I must exert myself in order to give in the same measure (8)_____ I have received and am still receiving. I am strongly drawn to a frugal life and am often oppressively aware that I am engrossing an undue (9)_____ of the labor of my fellow-men.

根据Nernst公式，有些与酸碱度有关的电极电势，其数值与pH具有线性关系， 如IO3--I2： 2IO3-+12H++10e＝I2+6H2O
当把[H+]换成pH，而其他物质的浓度都为标准态浓度，则有
再由E对pH作图，即得E-pH图。根据如下E-pH图(坐标未按比例)，回答问题：
(1)写出由IO3-／I2及I2／I-发生的氧化还原反应的方程式； (2)当pH为a、6、C时，分别指出(1)中反应所进行的方向； (3)计算上述反应的
(298 K)； (4)计算pH=b时的b值，此时反应的
为多少？ (5)E(Cu2+／Cu)的E-pH图从a开始变成了斜率为负的斜线，原因何在？ (6)根据图中的数据，求Cu(OH)2的Ksp。
