（2013盐城市）下列四个图像中，能正确表示对应变化关系的是
 |  |  |  |
| A．向一定量稀盐 酸中加水稀释 | B．一定温度下，向不饱和硝酸钾溶液中加入硝酸钾 | C．加热一定量的 高锰酸钾固体 | D．向盐酸和氯化镁的混合溶液中滴加氢氧化钾溶液 |
D
题目分析：A选项不能正确反应对应关系，因为酸溶液无论如何加水不能变为碱溶液；B选项是不能正确表示对应的关系，起点不能从0点开始；C选项是错误的叙述，锰元素的质量分数因为生成氧气的散失到空气中而增大；D选项向盐酸和氯化镁的混合溶液中滴加氢氧化钾溶液中，酸碱先发生中和反应，然后在发生盐碱反应产生沉淀，故是正确的叙述，故答案选择D，
