Chemistry and environment are closely related to people's lives. A school chemistry interest group collected some waste fixatives (mainly composed of Zn(NO3)).

(1) Insolubles can be separated by filtration, and solvents can be separated from solutes by evaporation. Evaporation.

(2) Zinc can react with silver nitrate to produce silver and zinc nitrate, and zinc can react with dilute sulfuric acid to produce hydrogen and zinc nitrate. sulphuric acid

(3) The purpose of adding proper amount of Ba(NO3)2 is to convert zinc sulfate into zinc nitrate.

The chemical equation of the reaction between zinc sulfate and barium nitrate is: Ba(NO3)2+ZnSO4═Zn(NO3)2+BaSO4↓
