[单选题]
The reversible reactiq(:q 5zs0,pjz, d nt bn,rp50vcc yv3to zo29 kny65khun between $N{H}_3$ and $H_{2}S{O}_4$ is:
$N{H}_3+H_{2}S{O}_4\rightleftharpoons N{H}_4^{+}+HS{O}_4^{-}$
Which compounds act as bases in the forward and backward reactions?

A. Base in forward reaction is $N{H}_3$ Base in backward reaction is $N{H}_4^{+}$
B. Base in forward reaction is $N{H}_3$ Base in backward reaction is $HS{O}_4^{-}$
C. Base in forward reaction is $H_{2}S{O}_4$ Base in backward reaction is $N{H}_4^{+}$
D. Base in forward reaction is $H_{2}S{O}_4$ Base in backward reaction is $HS{O}_4^{-}$


参考答案:  B


本题详细解析:
A base accepts a hydrogen ionx,z+ lc8 xd4giv)px4j v3bl 4s6ub za8, whereas an acid donates it. The base in the forward and backward reactions are therefore the species which gain hyb6zs+zx 8pc,gvjda4 )8ul4 4bi vlx3xdrogen ions during the reaction:$N{H}_{3}andHS{O}_4^{-}$ respectively. This question is moderately difficult as the student must recall the definition of a base and identify specific examples of bases in a reaction equation.
