25、(11分)王老师在化学课上经常组织同学们开展一些探究活动:

  (1)有一次王老师刚说为了探究酸的通性,需要先将浓硫酸稀释成稀硫酸。小明就立刻自告奋勇上台说要来完成这项稀释工作,王老师对他的学习热情给予了高度评价,不过当他用大量筒量取好20mL浓硫酸后,正准备将水加入到量筒中时,王老师立即进行了制止,并说他犯了两个原则性错误。请你写出小明的这两个错误        ;

               。

(2)一次王老师让甲、乙两组同学分别做常见酸和碱与指示剂反应的实验,所做的实验和使用的试剂如右图所示。实验后废液分别集中倒进各组的废液缸时,发现甲组废液呈红色,乙组废液呈蓝色。

请你分析废液的成分:甲组废液可能含有      ;

乙组废液中可能含有            。

假如将甲组的废液直接排入铸铁管下水道,会造成什么危害?

                。

(3)      自然界的物质每时每刻都在发生着各种各样的变化,而这些变化不仅与物质的性质有关,还与外界条件密不可分。因此人们利用这其中的规律,就可在生产、生活和科学实验中,通过控制条件来控制化学反应的发生。王老师要同学们结合初中化学已学过的知识,来说明以下问题:

     相关结论
    能说明此结论的实验事实
①反应物浓度越大,反应越剧烈
 
②温度不同,反应发生的情况不同
 
③有些变化受两个或两个以上条件控制,缺一不可。
