Question

Identify the precipitate (if any) that forms when KOH and Cu(NO3)2 are mixed.

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

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

Answer 5

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