There are no reaction between dilute sulphuric acid and zinc nitrate solution.

Explanation :
In aqueous solution, dilute sulphuric acid exists as H+(aq) and SO42-(aq) ions, while zinc nitrate exists as Zn2+(aq) and NO32-(aq) ions.
(1) H+(aq) and NO3-(aq) ions do not react, because HNO3(aq) ionizes in water to give H+(aq) and NO3‑(aq) ions.H
(2) H+(aq) and Zn2+(aq) ions do not react, because the cations repel each other.
(3) SO42-(aq) and Zn2+(aq) ions do not react, because ZnSO4­(aq) dissolves in water to give mobile SO42-(aq) and Zn2+(aq) ions.
(4) SO42-(aq) and NO3-(aq) ions do not react, because the anions repel each other.
