解析吸收二氧化硫一般选用NaOH溶液,A项正确;二氧化硫与水反应生成亚硫酸,使湿润的pH试纸显红色,所以湿润的pH试纸不褪色,B项错误;SO2水溶液使pH试纸变红说明其水溶液具有酸性,二氧化硫能使鲜花、品红溶液褪色说明有漂白性,使酸性高锰酸钾溶液褪色说明有还原性,与Na2S反应生成S说明有氧化性,C项正确;点燃酒精灯加热,褪色的品红溶液恢复红色,而KMnO4溶液不恢复颜色,可证明SO2使品红溶液褪色具有可逆性,使酸性KMnO4溶液褪色不具有可逆性,D项正确。
4.利用微型实验制取H2S和SO2,并探究硫元素之间的转化的装置如图。实验时挤压胶头滴管使稀硫酸滴在药匙中,然后倾斜试管使硫酸滴在FeS中与之反应。下列说法不正确的是( )。

C.该过程中的氧化剂与还原剂的物质的量之比为1∶2
D.实验一段时间后,试管壁上有淡黄色固体出现
答案B
(1)已知:①C(s)+O2(g)=CO(g) ΔH1= -110.5 kJ·mol-1,②C(s)+O2(g)=CO2(g) ΔH2= -393.5 kJ·mol-1,根据盖斯定律,①×2-②可得C(s)+CO2(g)=2CO(g) ΔH=[(-110.5)×2-(-393.5)] kJ mol-1=+172.5 kJ·mol-1;
