[单选题]
The correct sequence ic itb)6+mptv2l 8 85bydb,uaun decreasing order of pH for equimolar solutions is:

A.

C H_{3} C O O H > H C l > N H_{3} > N a O H

B.

H C l > C H_{3} C O O H > N a O H > N H_{3}

C.

N a O H > N H_{3} > H C l > C H_{3} C O O H

D.

N a O H > N H_{3} > C H_{3} C O O H > H C l

参考答案: D

本题详细解析:
NaOH is a strong base and has avnu ,* d ,y-c.dln6pwm.jg j5l high pH,

N H_{3}

is a weak base with a lower pH than NaOH.

C H_{3} C O O H

is a weak acid, HCl is a strong acid and so has the lowest pH.
