Four features of the 7 o-brw(vyl.uqf zco +:3k2dy 6wfw dg*zq8(t $HNO_3$ molecule are labelled a-d.
Why is one mole of $HNO_3$ able to react with one mole of NaOH?
A. Bond a can break to produce a hydrogen ion
B. ond b can break to produce a hydroxide ion
C. The charged nitrogen atom c can bond to a hydroxide ion
D. The charged oxygen atom d can bond to a hydrogen ion
参考答案: A
本题详细解析:
NaOH is a base so reacts wigx xn4w *;p9bqdvn*-nqx),a0;srmp vth a hydrogen ion. $HNO_3$ , nitric acid, releases a hydrogen ion through the breaking (heterolysis) of the O-H bond.
This question is moderately difficult as the student must recognise that NaOH is a base and $HNO_3$ an acid and correctly interpret a structural formula that may be unfamiliar.
