B) $0.01 M NaCl <0.01 M NaNO_2 < 0.01 M H_2S < 0.01 M H_2SO_4$
C) $ 0.01 M NaNO_2 <0.01 M NaCl < 0.01 M H_2S< 0.01 M H_2SO_4$
D) $ 0.01 M H_2S < 0.01 M NaNO_2 < 0.01 M NaCl < 0.01 M H_2SO_4$
Show Answer
Answer:
Correct Answer: C
Solution:
The acidic nature increases in the order. $ NaNO_2<NaCl<H_2S<H_2SO_4 $
