（3）钾原子最外层只有一个电子，容易失去一个电子而变成带一个正电荷的钾离子，钾离子的离子符号为 K +，2个钾离子即在钾离子符号前写上2，表示为2K+，故填：2K+；
（4）碘酸根离子(IO)的化合价为-1价，钠离子的化合价为+1价，根据化学式中正化合价在前，负化合价在后，正负化合价之和为零的原则，式碘酸钠化学式为NaIO3，故填：NaIO3；
（5）反应2中反应物是HIO3和K2CO3，根据流程图和质量守恒定律可知反应生成物为碘酸钾、二氧化碳和水，故反应方程式为：；该反应是酸和盐两种化合物相互交换成分生成另外两种化合物的反应，属于复分解反应，故填：复分解反应；
另一种制备KIO3的方法是将I2与KOH溶液共热，生成KIO3、H2O和另一种含碘化合物，I2与KOH溶液共热反应是氧化还原反应，碘元素的化合价从I2中的0价升高为KIO3中的+5价，所以另一种含碘化合物中碘元素的化合价应该将低，根据碘元素的化合价及质量守恒定律，可判断该含碘化合物为碘化钾，化学式为：KI。
20．【答案】（1）=
（2）
（3）复分解反应；
