Does a reaction occur when nicl2(aq) is added to a test tube containing zn(no3)2(aq)?

No reaction will occur when NiCl₂(aq.) is added to a test tube containing Zn(NO₃)₂(aq). As to a reaction to occur between two solutions that most probably undergoes a double displacement reaction , it has to meet the following requirements:

1) Precipitate formation

2) Gas generation

3) formation of a non-dissociating compound

But in the reaction of NiCl₂(aq) with Zn(NO₃)₂(aq), no above requirement is met, so no reaction takes place.

NiCl₂(aq.) + Zn(NO₃)₂(aq). >No reaction
