Hello and welcome OpenStudy. Can you determine if a reaction will occur? Hint: look at electronegativity.

anonymous · Answer

Cu(OH)2 ??   blue colored ppt??

aaronq · Answer

you wouldn't be able to predict the products based on electronegativity :S

you would just have to carry out a hypothetical double-displacement reaction and assess (with a solubility table) whether or not the products are soluble.

anonymous · Answer

@rvanclev what you'd do is swap the anions -ve ions between KOH and Cu(NO3)2. The anions are OH- ans NO3-.

I was thinking of double displacement. I just didn't know how to hint it to them. Thanks @aaronq
