下列实验对应的离子方程式不正确的是

  1. A.将碳酸氢铂溶液与过量的澄清石灰水混合: $\quad \mathrm{HCO}_{3}^{-}+\mathrm{Ca}^{2+}+\mathrm{OH}^{-}=\mathrm{CaCO}_{3} \downarrow+\mathrm{H}_{2} \mathrm{O}$
  2. B.将少量 $\mathrm{NO}_{2}$ 通入 $\mathrm{NaOH}$ 溶液: $2 \mathrm{NO}_{2}+2 \mathrm{OH}^{-}=\mathrm{NO}_{3}^{-}+\mathrm{NO}_{2}^{-}+\mathrm{H}_{2} \mathrm{O}$
  3. C.将少量 $\mathrm{SO}_{2}$ 通入 $\mathrm{NaClO}$ 溶液: $\mathrm{SO}_{2}+\mathrm{H}_{2} \mathrm{O}+2 \mathrm{ClO^{-}}=\mathrm{SO}_{3}^{2-}+2 \mathrm{HClO}$
  4. D.向氨水中滴入少量硝酸银溶液: $\mathrm{Ag}^{+}+2 \mathrm{NH}_{3} \cdot \mathrm{H}_{2} \mathrm{O}=\mathrm{Ag}\left(\mathrm{NH}_{3}\right)_{2}^{+}+2 \mathrm{H}_{2} \mathrm{O}$
